will work just as well for that. The cluster is usually also fine with not running the same version, since at least during the upgrade there will be nodes with different PVE versions in the same cluster. Just make sure your nodes run the same major ceph version. And before upgrading to 8, make sure all nodes are on 7.4[1].*major version, so PVE 7, PVE 8. Within the same major version it'll always be supported.Migration compatibility rules to keep in mind when planning your cluster upgrade:
- A migration of a VM or CT from an older version* of Proxmox VE to a newer version will always work.
- A migration from a newer Proxmox VE version to an older version may work, but is generally not supported.[1]
