How to upgrade a Proxmox 5 cluster to Proxmox 6

[gradinaruvasile]

Hi,

We have a 3 node Proxmox 5 cluster and we need to upgrade it to 6.
So, what is the procedure exactly?
It seems that we cannot add a new Proxmox 6 node to a Proxmox 5 cluster, so i just want to know how can we go about this.
Can we do the in-place upgrade of the nodes as we did before for existing nodes?
We already upgraded corosync to version 3 on all nodes.

Thanks.

Oh well. I wanted to add a new node to the cluster before migration.
I installed PVE 5.4 on the new node and joined it succesfully.
So i will just upgrade the cluster now.
