Can you add a 5.4 proxmox node to a 5.2-1 cluster with no HA enabled?

Currently, have a non HA proxmox cluster running on 5.2-1 and need to add another cluster node. However, I cannot get access to a 5.2-1 proxmox iso and only can access the 5.4 iso. Can you add a 5.4 proxmox node to a 5.2-1 cluster without problems? The reason I am doing this is because I would like to get the third node in the cluster before starting to upgrade them.

Personnaly, I always upgrade my nodes each month to last version.
(you can upgrade live your nodes without any impact on the running vms/ct. Reboot is only needed if you need to upgrade kernel for security)


You can keep them mixed, but if a vm has been started on a new qemu version, you'll not be able to live migrate it to older version.
