as a precaution it's not allowed to join a cluster when you already have VMs on a node (pve-cluster related issues).

just make a backup of the VMs on one node. transfer the backups somewhere, then clean the node and you'll be able to join.

edit: "clean the node" meaning remove the VMs

Hi, the easiest way is, Backup and then Restore to the new Cluster.
