Will changing the SSH Port on proxmox 3.4 and proxmox 4.2 servers cause any issues?

I want to secure our nodes more on these 2 versions and change the port. Could it break cluster config or cause any issue at all in doing so ?
 
If you have a "real" cluster with a "real" separated interconnect, then only change the SSH port on the non-cluster IP. You can have multiple listen IP:Port pairs in your ssh configuration.

Otherwise you need to configure a .ssh/config for root to be able to login into the other systems with a different port.
