FortiGate Firewall Migration in Dubai, UAE
Move firewall policy, routing, NAT, VPN and operational controls into a FortiGate environment through a planned migration process that gives equal attention to configuration conversion, business traffic, cutover risk, testing and rollback.
Direct answer for business buyers
FortiGate Firewall Migration is the controlled transfer and redesign of firewall configuration and network-security functions into a FortiGate platform. It is mainly used when replacing another vendor, moving from an older FortiGate to a newer model, changing topology, consolidating sites or modernising an existing security edge. Organisations should consider a formal migration process when firewall policy, NAT, VPN, routing, published services or compliance controls are important to daily operations. Before proceeding, confirm the exact source platform, target FortiGate, intended FortiOS version, interfaces, licenses, dependencies, outage tolerance, test plan and rollback method. Automated conversion can reduce repetitive work, but it does not remove the need for engineering review and acceptance testing.
What the migration service does
A migration project translates the existing firewall’s security intent into a FortiGate configuration that can be installed, tested and operated in the target network. The work may include discovery, configuration export, rule and object review, target design, conversion, manual correction, interface mapping, route and NAT validation, VPN recreation, administrative-access review, implementation planning, controlled cutover and post-change checks.
The exact tasks depend on the source vendor and the complexity of the environment. A small branch with a few policies is different from a headquarters firewall carrying multiple internet circuits, dynamic routing, site-to-site tunnels, remote access, server publishing, segmentation and high availability. The service therefore starts with evidence rather than assumptions.
Who it is designed for
FortiGate migration may suit IT teams that need to replace a legacy firewall, standardise several sites on Fortinet, refresh an older FortiGate model, move from hardware to a virtual deployment, change internet architecture, consolidate security policies or prepare a managed operational model.
It is particularly useful when the existing firewall contains years of accumulated rules and undocumented dependencies. Procurement teams also benefit from a defined migration scope because the hardware purchase, FortiGuard or support subscriptions, optics, rack accessories, professional services and maintenance-window requirements can then be separated clearly in the quotation.
Business problems a planned migration helps address
Legacy policy sprawl
Older firewalls often contain duplicate objects, disabled rules, broad services and temporary exceptions that became permanent. Migration is an opportunity to identify what should be transferred, what needs owner confirmation and what may be retired rather than copying every historical item without review.
Vendor translation differences
Firewall vendors use different object models, NAT logic, VPN settings, application controls and feature terminology. A direct text-for-text translation may not represent the same behaviour. The target configuration should be checked against the original business purpose of each important control.
Unclear cutover risk
Firewall replacement affects traffic at a critical control point. A maintenance window, outage communication, console access, configuration backup, rollback trigger and named technical owners reduce ambiguity when the network is switched to the target device.
Missing acceptance criteria
A migration should not be declared complete only because internet access works. Critical applications, inbound services, branch tunnels, remote access, DNS, identity, monitoring, logging and management paths need defined tests that reflect the real environment.
Core migration capabilities
Collect source backups, network diagrams, interface plans, routing information and dependency notes before changing the edge.
Translate supported rules, objects and related settings into a FortiGate-aligned structure, then inspect the result for gaps.
Review translated or rebuilt tunnels, source and destination NAT, published services and route dependencies.
Define implementation sequence, validation checkpoints, rollback criteria and communication responsibilities.
Test the services the organisation actually uses rather than relying only on device health indicators.

FortiConverter helps with conversion, but it is not the whole migration
Fortinet positions FortiConverter as a migration service and tool for translating configurations from supported third-party firewalls and older FortiGate environments into FortiGate configuration. Current Fortinet documentation also distinguishes the one-time FortiConverter Service from the FortiConverter Tool subscription. The service can be useful where the customer wants a conversion delivered through the FortiConverter portal, while the tool is oriented toward organisations or service providers performing conversions themselves.
That distinction matters because a converted file is an engineering input, not proof that every production dependency is correct. Some configuration items require manual handling. Certificates and certain token or external-device tasks can require separate procedures, and vendor-specific constructs may not have an exact FortiGate equivalent. A migration scope should therefore include review of warnings, target interfaces, object relationships, NAT direction, VPN parameters, routing, administrative access, security profiles, dynamic services and any custom behaviour on which the business relies.
Fortinet documentation currently notes that FortiGate-to-FortiGate conversion can use a free opt-in entitlement, while third-party-vendor conversion requires FortiConverter Service. Commercial terms and eligibility can change, so the exact source, target model and entitlement should be confirmed before assuming a license is included.
A practical FortiGate migration journey
Discover
Collect the running or saved source configuration, firewall inventory, diagrams, ISP details, interface mapping, VPN list, public services and key application dependencies. Confirm which device is authoritative if several backups exist.
Design the target
Confirm the FortiGate model, FortiOS target, interface use, VLANs, routing, HA design, management method, logging destination and required subscriptions. Decide what should be preserved and what should intentionally change.
Convert and review
Use an appropriate conversion method, inspect warnings, correct unsupported elements and compare important policies to the source. The review should focus on behaviour, not only object counts.
Prepare cutover
Back up both environments, document cable and interface changes, prepare console access, define rollback, communicate the maintenance window and build an acceptance checklist with business owners where needed.
Implement
Load or finalise the target configuration, change the traffic path in the agreed sequence and validate links, routing, NAT, VPN and critical services. Record deviations rather than improvising undocumented permanent fixes.
Stabilise and hand over
Review logs, session behaviour, alerts and stakeholder test results. Capture the final configuration, document approved changes and identify any follow-up tuning, licence, monitoring or support actions.
Policy translation should preserve intent, not clutter
Firewall policies accumulate history. A rule created for a temporary supplier project may still exist years later. A broad object group may contain addresses that no longer belong to the business. A service may have been widened during troubleshooting and never narrowed again. If migration simply reproduces this history, the new FortiGate begins life with the same uncertainty as the old platform.
A stronger approach classifies rules before cutover. Critical production rules should be identified and tested. Unused or questionable rules should be marked for customer review rather than silently removed. Shadowed rules, duplicate objects, stale comments and inconsistent naming can be rationalised when there is enough evidence and approval. The migration engineer should distinguish between technical cleanup and a security-policy redesign: they are related, but they are not the same task.
FortiGate policy structure may also differ from the source platform. Interface or zone relationships, application controls, user identity, policy order and NAT behaviour need to be understood in the target context. Where a source vendor combines functions differently, the migration may require several FortiGate objects or settings to reproduce the intended outcome. A one-to-one rule count is therefore not a reliable measure of completeness.
FourTeck can help organise the review around business ownership: which applications must work on day one, which published services need inbound testing, which rules can be challenged, and which changes should be postponed until after the new firewall is stable.
NAT, routing and interfaces are where small assumptions become large outages
Security rules are only one part of firewall behaviour. Source NAT determines how internal traffic appears to the internet or partner networks. Destination NAT and virtual IP definitions control how external users reach internal services. Static routes, policy routes and dynamic-routing protocols decide where sessions leave the firewall. Interface addressing, VLAN tags, link aggregation, zones and HA links define the paths on which those settings operate.
During migration, each of these areas should be mapped to the target topology rather than copied in isolation. A new FortiGate may have different physical port names or port speeds. The customer may use the project to move to fibre uplinks, redesign VLAN trunks, change WAN providers or introduce an HA pair. Those changes alter the relationship between converted policy and the actual cabling. They should be documented before the maintenance window.
Routing deserves particular attention when several paths exist. Default-route behaviour may appear simple in a lab but interact with SD-WAN, BGP, OSPF, policy routing, asymmetric paths or upstream failover in production. If a migration changes route preference or next-hop reachability, a policy may be correct yet traffic may still fail. Test cases should therefore include routing outcomes, not only firewall-rule matches.
The same applies to public services. A website, mail gateway, VPN portal or vendor application can depend on ISP addressing, upstream NAT, DNS, certificates and allowed source ranges. Confirming these dependencies before cutover is more reliable than discovering them after external users report a problem.
VPN migration needs peer-by-peer validation
Site-to-site VPNs often represent the hidden workload in a firewall replacement. A network may contain tunnels to branches, cloud environments, suppliers, payment platforms, managed-service providers and remote facilities. Each peer can use different encryption parameters, lifetime values, selectors, routing methods, authentication credentials and monitoring expectations.
Conversion can reproduce supported configuration elements, but the remote peer remains outside the new firewall. A successful cutover therefore depends on both sides agreeing. Pre-shared keys must be available, certificates may need to be transferred or reissued, peer addresses must match, and remote administrators may need to change settings if the local public address or proposal changes. Route-based and policy-based designs can also require different target handling.
Remote-access VPN adds another set of dependencies. User groups, identity sources, multi-factor authentication, client versions, split-tunnel routes, DNS settings, portal permissions and certificate trust can affect the user experience. If the migration also changes FortiClient or authentication architecture, that should be treated as an explicit project stream rather than an incidental firewall setting.
For business-critical tunnels, FourTeck recommends a peer inventory with owner, remote contact, local and remote networks, authentication method, current status and a cutover test. This turns an undocumented collection of tunnels into a manageable acceptance plan.
Ideal business environments and migration use cases
Legacy firewall replacement
Organisations retiring older security appliances can use migration to preserve required connectivity while revisiting accumulated configuration and mapping functions to a current FortiGate design.
FortiGate hardware refresh
A newer model may have different port names, hardware capabilities and FortiOS requirements. FortiGate-to-FortiGate migration should account for those changes instead of assuming the source file can be loaded unchanged.
Multi-site standardisation
Regional businesses may migrate mixed firewall platforms into a common FortiGate operating model. Shared standards can be introduced while preserving legitimate site differences.
Data-centre edge transition
High-value server publishing, inter-zone traffic, routing and HA requirements make data-centre migrations suitable for a staged plan with deeper application-owner testing.
Security policy consolidation
Mergers, office consolidation and network redesign can create overlapping firewall rules. Migration can support a controlled rationalisation process where ownership and risk are understood.
Virtual or cloud transition
When moving security functions into a FortiGate VM or supported cloud architecture, interface, routing, licensing and platform-network dependencies should be included in the design.
Integration and operational considerations
A firewall rarely operates alone. Before migration, identify systems that exchange configuration, identity, logs or control signals with the existing device. Examples can include FortiManager, FortiAnalyzer, SIEM platforms, syslog collectors, authentication servers, RADIUS, LDAP, TACACS+, DNS, NTP, certificate authorities, vulnerability scanners, monitoring platforms and ticketing workflows. Not every environment uses these components, but those that do can create dependencies beyond traffic forwarding.
Administrative access should also be redesigned deliberately. Management IP addresses, trusted hosts, role-based administrator accounts, MFA, out-of-band access and backup procedures can change during a replacement. A migration is a poor time to discover that the only management path depends on the production interface being changed. Console access or another tested recovery method should be available for the change window.
Logging and reporting need acceptance criteria. If the source firewall forwards events to a SIEM, the target FortiGate should be checked for time synchronisation, source identity, log destination, required event categories and parsing expectations. If FortiAnalyzer is introduced at the same time, storage, licensing, registration and retention policy become part of the wider scope.
Where FortiManager is used, determine whether the target is imported after migration, built under central management from the start, or handled through an existing administrative domain and policy package. This decision affects configuration ownership and change workflow. A local device configuration that works correctly can still create operational conflict if the management platform later overwrites it.
FourTeck can include these touchpoints in the discovery process so the migration is assessed as an operational system change rather than a single appliance swap.
Buyer questions to resolve before ordering migration work
What exactly is the source?
Provide vendor, model, software version, HA status and a current configuration export. If a central manager controls policy, identify that source of truth as well.
What is changing besides the firewall?
New ISP circuits, public addresses, VLANs, switches, rack position, optics or routing architecture increase the scope and should be known before conversion begins.
Which services are critical?
Identify applications, VPNs and published services that must be tested during the maintenance window, with a business or technical owner where possible.
How much change can be combined?
Decide whether policy clean-up, new security profiles, SD-WAN, HA redesign or VPN changes should happen during the same window or after the base migration stabilises.
What is the rollback trigger?
Define when the team stops troubleshooting and returns to the source firewall. A rollback decision is easier when the criteria are agreed before the outage starts.
Who owns acceptance?
Network teams can verify technical health, but application, server, voice, cloud and business owners may need to confirm their services before the change closes.

How FourTeck can assist with scoping and execution
FourTeck can help turn an informal request such as “replace this firewall” into a migration plan that identifies the source configuration, target platform, business dependencies and change responsibilities. The first step is usually a requirement review. That can include firewall inventory, model and FortiOS information, policy and object counts, VPNs, routing, internet services, HA, logging, management platforms and the proposed target design.
From there, the scope can distinguish conversion from implementation. Configuration conversion may be handled through an appropriate FortiConverter route or manual engineering, while implementation services cover target preparation, migration review, change-window activity and agreed validation. Where the project includes a new FortiGate purchase, FourTeck can also discuss model selection, subscriptions, accessories, optics and support requirements. Availability and lead time should be confirmed at quotation stage rather than assumed.
For complex sites, FourTeck can help structure pre-change testing and stakeholder sign-off. This may include a list of internet destinations, internal application paths, inbound published services, branch VPNs, cloud tunnels, remote-access users, DNS and identity checks. A clear acceptance list makes troubleshooting more focused because the team knows which outcomes matter most.
The exact professional-service scope remains project dependent. Customers should share access restrictions, preferred implementation hours, change-control requirements, onsite or remote expectations, documentation needs and post-change support requirements when requesting a quotation.
UAE availability and support guidance
FourTeck can coordinate FortiGate Firewall Migration requirements for organisations in the UAE, including discovery, target sizing discussions, conversion planning, configuration review, cutover preparation, testing and support scope. Service availability depends on the required skills, source platform, project complexity, access method, maintenance window and scheduling. If hardware, FortiConverter entitlement, FortiGuard subscriptions or FortiCare support are part of the project, those items should be confirmed in the same commercial review.
Contact FourTeck to confirm current UAE availability. Delivery and project coordination can be discussed after the exact target model, quantity, subscription term and implementation requirements are known. Installation and configuration tasks should be written into the quotation when required rather than assumed to be part of a hardware purchase. Buyers can review FourTeck firewall services and the firewall product catalogue while preparing the request.
Dubai, Abu Dhabi, Sharjah and Ajman coverage
Businesses in Dubai, Abu Dhabi, Sharjah and Ajman can discuss FortiGate migration planning, hardware refresh, configuration services and change-window coordination with FourTeck. The practical delivery model may be remote, onsite or a combination depending on the firewall location, console access, security policy, maintenance period and commercial scope. For data centres and controlled facilities, buyers should share visitor procedures, rack access rules, escort requirements and approved change hours early so the implementation plan reflects real site constraints.
For offices with several branches, it may be more effective to complete one representative migration first, record lessons, and then plan subsequent sites with controlled variation. The correct approach depends on network similarity and business tolerance for change. Firewall Dubai by FourTeck provides a starting point for UAE firewall requirements.
GCC Availability
FourTeck can assist organisations planning FortiGate migration work across GCC operations where the requirement includes a defined destination, target firewall, licensing need and implementation scope. Regional projects may involve the United Arab Emirates, Saudi Arabia, Kuwait, Qatar, Bahrain or Oman, but each location can have different procurement routes, lead times, access procedures and operational calendars. For a useful quotation, share the destination country, source firewall platform, target FortiGate model or sizing requirement, quantity, desired subscription term, preferred deployment window and whether the work is expected to be remote, onsite or coordinated with a local team.
Multi-country migrations benefit from a common configuration standard and a documented method for local exceptions. ISP addressing, VLANs, site-to-site VPN peers, public services, timezone settings and local application dependencies can differ even when branches use the same firewall model. FourTeck can help organise requirement review, conversion scope, configuration standards, rollout sequence and renewal planning. Product availability, licensing, delivery schedules, service visits, project scope and vendor lead times remain country, model, quantity and requirement dependent. Customers with Kuwait requirements can also review FourTeck Kuwait resources while confirming the final project scope.
Africa Availability
For organisations with operations in Africa, FourTeck can support the planning side of FortiGate firewall migration by helping teams define the source environment, target platform, licenses, accessories, configuration scope, deployment dependencies and support expectations. Regional projects often need more preparation because shipping arrangements, power standards, remote-access quality, local engineering availability, site security procedures and vendor lead times may vary significantly. Buyers should provide the destination country, exact firewall requirement, quantity, preferred implementation period and any expectation for onsite installation, remote configuration, migration assistance or post-change support.
East Africa and other regional deployments may also involve branch standardisation, VPN consolidation and central management. In those cases, a reusable migration baseline can reduce inconsistency, but every site still needs local verification of interfaces, addressing, ISP details and business services. Availability and fulfilment can depend on destination, product model, quantity, license region, shipping arrangements, installation scope and local project conditions. FourTeck does not treat those variables as guaranteed. Organisations can review FourTeck Africa and FourTeck Kenya for regional contact pathways while confirming the final migration requirement.

Why businesses contact FourTeck for migration planning
The practical value of a migration discussion is clarity. A firewall change usually crosses procurement, networking, security, application ownership and operations. The buyer may know that an existing firewall must be replaced but may not yet know which rules are active, how many VPN peers exist, whether the target interface layout is correct, which FortiGuard subscription is required or how long the business can tolerate an outage. FourTeck can help turn those unknowns into a scoping checklist.
Model and licence selection can then be connected to the migration rather than treated separately. If a target FortiGate must support additional inspection, higher VPN usage, new fibre interfaces, HA or central management, those requirements belong in the bill of materials before the purchase order. Likewise, if a FortiConverter entitlement is required for the source-to-target path, that should be confirmed before the planned conversion date.
Migration planning also benefits from an independent review of assumptions. A source rule may appear redundant but support a monthly finance process. A dormant VPN may be required for disaster recovery. A public NAT entry may be tied to external DNS controlled by another supplier. FourTeck can help identify where customer ownership or third-party coordination is needed so these dependencies are resolved before the implementation window.
The goal is a supportable handover: a working target configuration, documented exceptions, retained backups, known follow-up tasks and a clear point at which the project moves from migration into normal operations.
What organisations usually want to know before moving to FortiGate
Buyers researching firewall migration rarely ask only whether a configuration can be converted. They want to know how much of the old environment will survive the move, which settings need manual work, whether VPNs and public services will continue to operate, how much downtime to plan, what information an engineer needs and whether the new FortiGate should reproduce the old design or improve it. Those questions are more useful than a generic promise of “easy migration” because they reveal the decisions that control project risk.
Create an authoritative inventory of what the firewall does today. Include business-critical traffic, not just configuration objects. A technically perfect conversion can still fail a business requirement that was never identified.
Can FortiConverter migrate everything automatically?
No migration tool should be treated as a guarantee that every source feature has a direct target equivalent. Fortinet publishes supported conversion information and also documents manual prerequisites for some items. The converted configuration should be reviewed for warnings, unsupported features and assumptions. Certificates, external systems, custom scripts, special VPN behaviour and vendor-specific security features may need separate work. The correct question is not “did the tool finish?” but “does the target configuration reproduce the required behaviour?”
Is FortiGate-to-FortiGate migration simpler than changing vendors?
It is usually more consistent because the configuration models share FortiOS concepts, but it still requires care. Hardware generations can have different interfaces, supported FortiOS versions and feature behaviour. A source configuration may refer to physical ports that do not exist on the target. The refresh may also introduce new WAN links, VLANs or HA. Fortinet currently provides a FortiGate-to-FortiGate conversion path, yet the final file should still be checked against the target device and network design.
How should a business estimate downtime?
There is no responsible fixed answer without knowing the environment. A branch with one internet line and a few rules has a different change profile from a headquarters with HA, several ISPs, BGP, dozens of VPNs and public services. Downtime planning should consider physical installation, cable moves, configuration load, interface activation, route convergence, peer changes, testing and the point at which rollback becomes necessary. The migration quotation should identify the expected implementation method rather than advertise an unsupported universal duration.
Should old firewall rules be cleaned up during the move?
Often yes, but cleanup needs ownership. Removing a rule solely because it has little recent traffic can be risky if the application runs monthly, quarterly or only during incidents. A useful process marks stale or questionable rules, identifies an owner, records evidence and decides whether the rule is removed before migration, excluded from the target or retained temporarily with a follow-up review. This balances security improvement with operational continuity.
What source platforms are commonly considered?
Fortinet currently describes FortiConverter support for a range of firewall vendors including Check Point, Cisco, Forcepoint, Juniper, Palo Alto Networks, SonicWall, Sophos and WatchGuard, as well as FortiGate-to-FortiGate migration. Exact supported versions and configuration elements can change. Buyers should provide the source vendor, model and software version so conversion compatibility can be checked against current Fortinet guidance instead of assuming every historical release is covered.
What makes a migration quotation accurate?
An accurate request identifies the current firewall, target model or target sizing requirement, number of sites, HA status, policy and object complexity, VPN count, routing protocols, public services, management tools, desired security subscriptions, maintenance window, onsite or remote expectation, documentation requirement and post-change support. Sharing a configuration export under an agreed secure method can materially improve scope quality because it replaces guesswork with evidence.
Another common buying question is whether the migration should be treated as a direct replacement or a network redesign. A direct replacement tries to keep topology and traffic behaviour stable while changing the firewall platform. A redesign deliberately changes zones, addressing, routing, security profiles, remote access or internet architecture. Both approaches can be valid, but combining too many changes can make troubleshooting harder because several variables move at once. Organisations with strict continuity requirements often benefit from separating the base firewall migration from later policy optimisation unless there is a compelling reason to combine them.
Buyers also search for migration “cost,” yet professional-service pricing cannot be inferred reliably from the firewall model alone. Effort depends on configuration complexity, number of stakeholders, conversion method, required testing, geographic coverage and whether the project includes hardware, licensing, installation, HA, VPN coordination or after-hours work. Public prices for FortiConverter entitlements vary by target model and should not be confused with the complete cost of engineering a firewall replacement. FourTeck can prepare a tailored quotation after the target and service scope are defined.
Questions that reveal whether a migration plan is ready
These questions go beyond a standard FAQ. They help a buyer find missing information before it becomes a change-window problem.
Do we know which configuration is authoritative?
If the firewall is centrally managed, the local running configuration may not tell the whole story. Confirm whether policy comes from FortiManager or another vendor’s manager, whether pending changes exist, and when the last backup was taken. Using an outdated export can cause the migration team to recreate a network state that no longer matches production.
Have we identified traffic that cannot be tested by the network team alone?
Many failures look like network problems but require application knowledge. ERP interfaces, payment services, supplier APIs, voice systems and specialised remote-access workflows may need an owner to validate them. The test plan should name those owners and define what a successful transaction looks like.
Are public IP addresses staying the same?
A new ISP or address range changes more than the firewall. DNS records, partner allow lists, VPN peers, SaaS restrictions, email reputation settings and published-service certificates can be affected. If public addresses change during the migration, treat external coordination as part of the project schedule.
Is high availability being introduced or modified?
HA adds cabling, heartbeat interfaces, device synchronisation, failover testing and upstream/downstream design questions. It should not be assumed that a source cluster maps identically to the target. Confirm the FortiGate HA design and how switches, routers and WAN circuits connect to both members.
What will happen to certificates and authentication?
Certificates may support administrative access, VPN, SSL inspection or published applications. Identity may rely on LDAP, RADIUS, SAML, local users or external MFA. These elements often involve secrets and trust relationships that are not safely recreated by simple policy conversion. Prepare them as controlled migration items.
Can we roll back physically as well as logically?
A backup file is useful only if the original firewall can be restored to the traffic path. Confirm power, cables, ports, public addresses, upstream ARP behaviour and console access. If the source appliance is removed from the rack or recabled extensively, rollback may take longer than expected.
Which changes should wait until after migration?
New security profiles, segmentation, SD-WAN and policy tightening can deliver value, but combining all of them with the appliance replacement can complicate fault isolation. Decide which improvements are essential to the target design and which can be introduced after the base network is stable.
What evidence will close the change?
A useful handover includes the final configuration backup, migration notes, test results, known exceptions, remaining actions and ownership. Monitoring for a defined period after cutover can reveal low-frequency dependencies that did not appear during the immediate acceptance tests.
Frequently Asked Questions
Can FortiGate Firewall Migration move rules from another firewall vendor?
Yes, supported third-party configurations can be converted toward FortiGate using FortiConverter, and manual engineering can address items outside the supported conversion path. Exact compatibility depends on the source vendor, source version, configuration elements and target FortiOS, so the source configuration should be checked before the project is quoted as a simple automated conversion.
Can FourTeck migrate an older FortiGate to a newer FortiGate?
Yes. FortiGate-to-FortiGate migration can include configuration conversion, interface remapping, target-model review and validation. Hardware differences, FortiOS versions, port naming, licensing and any topology changes still need to be considered before the new configuration is treated as production ready.
Does FortiConverter eliminate all manual migration work?
No. FortiConverter can reduce repetitive conversion effort, but Fortinet documents manual prerequisites and feature-specific limitations. Engineers should review conversion warnings and validate VPN, NAT, routing, certificates, interfaces, security features and external integrations rather than assuming the converted file is complete.
How much downtime is required for a FortiGate migration?
Downtime is project dependent. It varies with site complexity, physical installation, interface changes, HA, routing, VPN peers, public services, testing and rollback requirements. FourTeck can help define a maintenance-window plan after reviewing the source and target environment, but a fixed universal duration should not be assumed.
What information is needed for a migration quotation?
Provide the source vendor, model and software version, current configuration export, target FortiGate model or sizing requirement, site count, HA status, routing, VPN count, public services, expected maintenance window, required licenses and whether configuration, installation, testing or post-change support is needed.
Can firewall policies be cleaned up during migration?
Yes, but rule removal or tightening should be evidence based and approved by the relevant owner. Migration can identify duplicates, stale objects and questionable rules, while business-critical or uncertain items can be retained temporarily and reviewed after the new FortiGate is stable.
Are VPNs included in FortiGate migration work?
VPN migration can be included when it is part of the agreed scope. Site-to-site and remote-access VPNs require peer, authentication, route, certificate and user dependencies to be reviewed. Third-party peer coordination may also be required if addresses, proposals or authentication details change.
Is FortiConverter licensing always required?
No. Licensing depends on the conversion path. Fortinet currently documents a free opt-in entitlement for FortiGate-to-FortiGate conversion, while third-party-to-FortiGate conversion requires FortiConverter Service. Exact eligibility and commercial terms should be confirmed for the target device and current vendor policy.
