Build the new FMC using the proper sizing for the FMCv license you own. That includes the proper compute, memory and disk resources. Then temporarily change the model using configure-model-sh (run as root user). Use the migration tool to completion and then change the model back to the original correct version.

I don't see any problem with that, however, recommended is 64 GB. I suggest only downgrade post migration to be on the safer side and don't forget to take a backup.

You can use this script as root from the FMC expert cli:

/var/sf/etc/model-info/configure-model.sh
