Hey all, I just want to be as prepared as possible. I have a production CM4.1.3 cluster with two nodes.
I just finished building and testing my new 6.1.2 cluster. I have new hardware and they are running on the same VLAN but with different IP addresses. I've tested Attendant Console and Extension Mobility and that is working. The licensing is done.
My plan is to shutdown the old cluster, renumber the new cluster to be what the old one was, and hope it all works.
My biggest concern right now are the gateways. I run MGCP now with most gateways running IP Voice 12.3T. Is there anything I should be doing to my gateways prior to the swap?
