We planned to migrate from FMC2500 to FMC2700. Even though we have received the FMC2700 we have decided to make an intermediate step over FMCv because we want to make a whole new design and do not want to run on unsupported FMC2500 in the mean time.
After Migration we want to upgrade to version 7.2.8 (recommended) and with that we can manage some production FTD with version 6.6.x (really old I know)
But what if we later want to upgrade to 7.4 or even newer??
So my question is, can we migrate to 2 x FMCv?
Migrate the first normal (same IP/hostname)
On the second restore same backup file, but change the IP/Hostname and remove all 7.x FTDs before enabling network connectivity again?
