Yes, this is one of the common use cases.

You can back up version X and perform the migration to version Y. If anything goes wrong during the migration, you can simply restore version X from the initial backup (you will, of course, need to downgrade to the original database version before restoring).

Hi, Portabase handles database backup and restoration. It does not manage the migration process, so it depends on the type of database and whether migration is handled automatically or not.
