I'm taking a customer from UCM Business Edition 6.1 to full UC 7.1.2 on 3 servers. I am unable to find any documents about this process, so I wanted to run my plan by the forum to see if there are any holes in it.
First, I'm upgrading BE to 7.1.2. Then, using the hardware replacement guide for UCM and Unity Connection, I'm going to build a new UCM publisher and Unity Cxn both w/ the IP address of the current server. Then I'll do a disaster backup of UCM and Unity and restore them to their respective servers (this will be on a separate network of course).
UCM and Unity Cxn Hardware Replacement Guides
Then I'll change the IP addresses of Unity Cxn and UCM Publisher for their new segment. At that point, I'll install the servers in their new location and swing DHCP to the new cluster. After everything bakes for a day or so, I'll re-install the current UCMBE server as subscriber 1 in the new cluster and shift the phones accordingly.
Does anybody see any problems w/ this plan?
AFAIK, you will not be able to restore data back onto the CM and CX server separately. When you run DRS on the CUCMBE, it will spit out files which will be used by both CM and CX. I think your best bet will be to do a fresh build.
