Question - Run PVE Ceph & Non-PVE Ceph within the same cluster?

Hi there,

We're planning on migrating one of our Ceph platforms to new Ceph versions, this currently runs 'regular' Ceph from the official download()ceph()com repository on Ubuntu 22.04.
Now we'd like to change this out for Proxmox VE Ceph, primarily because of the extra bug-fixes & cherry picks that the regular Ceph repository does not include.

Our question at the moment is; 'Can we run these Ceph versions together, probably mismatched between different Reef versions'. Unfortunately we've not got any extra hardware laying around that we could prepare and simply `ceph-volume lvm activate all`, it has to be migrated node-per-node.
Has anyone else done this before, or ran into an issue with this?

Thanks!
