There's also 8+ year old unresolved bugs like this in OpenStack Cinder
that will bite you if the relocated mons have new IP addresses:

Tripling down on what others have said: would advise against
redeploying mons unless you need to...

FYI: you can relocate the OSDs without having Ceph spew bits about by
setting noout, stopping the OSDs to be moved, physically moving the
underlying drive(s) to another host, running `ceph-volume lvm activate
--all` on the new host, and unsetting noout.
