[ceph-users] permission errors rolling back ceph cluster to v13

Hi, I have been running into some connection issues with the latest ceph-14 version, so we thought the feasible solution would be to roll back the cluster to previous version (ceph-13.0.1) where things are known to work properly. I'm wondering if rollback/downgrade is supported at all ? After
