2nd Relay Node question?

Quick question if I may. My Block producing and relay node are both VM’s. I want to clone my relay node and create a VM for a second relay. If I do what changes do I need to make to the configuration of the second relay before I put it live on the network? I am just thinking that this will be much quicker than configuring one from scratch?

Port number, assuming IP is via DHCP otherwise you obviously need to change that too. You also need to set up the topology File so the relays point to each other and the block producing node. The block node obviously needs to point to both relays.
You then need to re-register your pool so both relays are advertised.
