I'm in the middle of an OpenStack migration (obviously Ceph backed) and stumble into some huge virtual machines.

To ensure downtime is kept to a minimum, I'm thinking of using Ceph's snapshot features using rbd export-diff and import-diff.

However, is it safe (or even supported) to do this across versions?

The source cluster is running 10.2.11 and destination is 12.2.11

Why just not migrate your VM's? k
