We don't use mesh, but upgrades of PVE5 to 6 including Ceph have been 
almost trouble free. After upgrade and booting with new kernel, check 
that network interface names have not changed; we had some issues with a 
10G network card bonded with a 1G interface that we only found by the 
hard way (reboot of 1G switch...).

Also, we're having issues with Proxmox tooling for replacing failed OSDs 
with wal/db in a shared SSD drive; we have to do it manually:
