Clarification: Adding empty node to existing cluster

[xvzacrw]

I just want to get clarification on the process of adding nodes to a cluster. The exact phrasing of the documentation leaves me unsure.

A new node cannot hold any VMs, because you would get conflicts about identical VM IDs. Also, all existing configuration in /etc/pve is overwritten when you join a new node to the cluster. To workaround, use vzdump to backup and restore to a different VMID after adding the node to the cluster.

A user in this thread says I don't need to backup or even stop existing VMs.

My new node does not have any VMs, but my existing cluster does. Is it going to overwrite the configuration in /etc/pve on the new node, or on my cluster? It doesn't say the cluster can't contain any VMs, so I am assuming I will be fine to add an empty node to my cluster. Just want to make sure I am understanding this correctly. Thanks!

yes (it will copy the data from the existing cluster).

or on my cluster? It doesn't say the cluster can't contain any VMs, so I am assuming I will be fine to add an empty node to my cluster. Just want to make sure I am understanding this correctly. Thanks!

yes, it I will be fine to add an empty node to my cluster.
