Is image migration between ceph datastore pools possible?

there are some previous questions about migrating images between ceph storage pools, but it’s not clear to me whether this is actually supported. we’re running open nebula 5.8.5 with ceph underneath. attempts to clone an image from one pool to another, either via terraform or manually, yields an error. i haven’t tracked down the exact error or found more context yet.

should this actually work/is it supported? any details i could provide to help figure out if this will work?
