Firewall Migration Service


Organizations migrate firewalls to adapt network security measures to better meet their current requirements. If a business can’t handle system security migration and migration of the firewall by itself, a way out is turning to the professionals who provide a firewall migration service tailored to specific business needs.


The major reasons for firewall migration include:
Upgrading from Legacy Port-Based Systems Changing the Firewall Vendor Switching Firewall Plans or Packages
Replace your old firewall (like Cisco ASA, MikroTik, D-Link, or Proxy Servers) with newer, safer technology with more capabilities Transition from one next-generation firewall vendor to another (e.g., from Check Point to Palo Alto) whose offer suits you better Move to a different plan provided by the same vendor to get an upgrade or to make a shift to a more cost-effective option


Although most vendors have their own firewall migration tool to help you automate migration, the process has plenty of intricacies. A successful migration is not just a few checkbox ticks.

Each migration case has to be approached by considering the specifics of the new system you’re shifting to. To get the most of the new functionality, you must:

  • thoroughly analyze the existing firewall configuration
  • plan the migration in detail
  • apply the firewall migration best practices
  • have in-depth knowledge of how the new system works

This way, you don’t just transfer the exact same configuration from your old firewall. Instead, you’ll migrate the essentials and utilize all the new security features and functionality of the new firewall. This approach will let you

If you have doubts about how to do things right, using a firewall migration service provided by experienced network security professionals like OutsourceIT.PRO can keep you on the safe side.

Seeking firewall migration consultations?


How long does firewall migration take? Honestly, it depends on lots of factors, as many parts are configured from scratch either way. However, here are a few estimates of the typical firewall migration timeframes:

🕗 - Simple configuration (for example, migrating the rules and user Internet access policies of a firewall with simple configurations can take 1-2 working days and up).

🕛 - Data center firewalls (migrating the firewall of a data center usually takes much longer, 7 or more working days without system optimization, but the duration is entirely based on the scope, how many rules are present, and the complexity of the firewall policy migration in general).

⏱️ - Migrating to another vendor (most vendors have firewall tools that can be used to speed up the migration process, yet it’s not a matter of a few clicks since you never transfer everything one for one; you must first review your existing configurations and rules, know how to apply migration tools, and make changes, otherwise the migration won’t be effective).

OutsourceIT.PRO has several firewall migration service packages you can select:


1When should I switch from one firewall vendor to another?
Businesses often switch to other firewalls if the existing vendor has poor technical support. Another common reason is if the current solution can’t deliver the needed bandwidth and performance, so you decide to migrate to a different plan by the same vendor or to another vendor altogether.
2What are some best practices for firewall migration?
Having a detailed migration plan that is based on the analysis of the current firewall configurations and the new system’s peculiarities can help make the firewall migration process and transition smoother. It is also integral to have a backup, know how to prevent potential disruptions or connection issues, and test the configurations before moving them to the production environment.
3Can I use a migration tool to migrate the firewall myself?
Many of the firewall vendors have a secure firewall migration tool for automation, but the process isn’t too straightforward. As such, you have to know how to use the Fortinet or Palo Alto firewall migration tool to transfer data securely without downtime or losses. Not to mention that it shouldn’t make your systems vulnerable even for short periods of time. Therefore, it might be reasonable to consult with the professionals or get their assistance.
4Is it worth migrating my firewall to a new one just as it is?
Firewall migration generally doesn’t work like that, I.e., you don’t just move your configuration exactly as it is from one firewall to another. This is your opportunity to review your existing configurations, get rid of unnecessary rules, and make tweaks to get the most out of what your new firewall offers.
5Is firewall migration as simple as “copy-paste”?
Actually, no, that’s far from the truth because the firewall configurations usually have to be combined or partially changed during migration. Many parts are reconfigured and set up from square one, such as the network part, including addressing and routing. Giving examples of what might be migrated practically unchanged, the traffic routing rules.
6What are the common challenges during firewall migration?
One of the migration challenges is transferring without analyzing the existing rule base. In most cases, there are unused objects or services that can be deleted to boost performance. If they aren’t deleted, you move old ineffective rules and dead weight to the new firewall. Technical complexity and lack of previous experience in migration are among other challenges.
