What does it show if you do 'ceph versions'?

Also, there is a way that you can upgrade individual daemons via "staggered" upgrade...

"ceph orch upgrade --daemon-types <type1,Type2, etc.>"

I have in fact already tried that, initially limiting the upgrade to mgr and mon daemons. Same as without the restriction - with "--ceph-version 20.2.0" the upgrade fails immediately with "ceph cannot downgrade to a dev release", with "--image quay.io/ceph/ceph:v20.2.0" the "cannot downgrade" appears in the upgrade status. -- MS
