Hello.

We've been running a 2-node drbd cluster, and need to change to 3+ .

this is our current cman line in /etc/pve/cluster.conf:
Code: 
 <cman expected_votes="1" keyfile="/var/lib/pve-cluster/corosync.authkey" two_node="1"/>

Has anyone successfully migrated from a 2 node to 3+ node cluster?

Are there any known issues ?

i've done it before, cant remember if i had to manually remove it or if pvecm add <node> did it for me but the two_node=1 section was removed and the expected votes count was increased
 
I would love to hear if this worked. I will be doing the same thing later today. Loving Proxmox and decided to convert my apache server to Proxmox and virtualize apache.
