Firewall Migration Tool - How to avoid interface group creation

Chess Norris — Thu, 19 Feb 2026 09:32:22 GMT

Hello,

Every time I use FMT, it seams like the tool automatically create interface groups which I don't want to use.
I want to use interface zones and no interface groups. To remove the interface groups after a migration, I first need change all configuration that are referencing those interface groups and that can be time consuming.

Can this be avoided if I manually configure the interfaces on the FMC and the target FTD before running the migration tool?

Thanks

Hey @Chess Norris , The interface groups are optional. When using the auto-create option, uncheck the interface group checkbox and keep only the security zone checkbox selected. This will create only a zone, not the interface groups.

Thank you @Nishad I didn't know that there was an option to uncheck the interface groups, but I will try this the next time I do a migration.
