3 node cluster advice

[brosky]

I have the following setup, independent machines:

pve1 - proxmox v4.0
pve2 - proxmox v4.1.1
pve3 - proxmox v5.0

I want to make a new cluster with v6 and so far I did:

1. migrate all vm's from pve1 to pve3 [done]
2. reinstalled pve1 with v6 [done]
3. started migration of all vm's from pve2 to pve1 [in progress]
4. reinstall pve2 and migrate back some of the machines
5. migrate all vm's from pve3 to pve2, reinstall
6. try to evenly redistribute the vm's

How can I optimize this ?

I had previously some bad experiences with proxmox cluster due to random issues and I presume that now it's more mature than v4.0

be sure to create the cluster on the first node, and don't join a node with a vms on it. join straight after install and next you can move vms on it

Well, I have now VM's on all of them. I should empty a node, reinstall, create a "cluster" on it and then move VM's there (via backup/restore) and only after I have the second node empty, I can join it ?
