the new uuid or path after migration needs to be updated in the backed-up volumes metadata if any backups existing for them? any case path might also change?

[Pearl1594]

The new UUID / path for the backed up volume doesn't need to be updated as the uuid - points to the volume UUID - which is always the same on subsequent backups, and the path points to the backup path - which shouldn't vary even if volume is migrated. I don't see the path of the backup changing.
