[cisco-voip] Upgrade 6.1 to 8.0

[Bill Riley]

How about if I isolate the new server, upgrade it and remove the existing
subscribers from the server group. The new cluster will have a new IP but
all the upgraded information. Then move the new cluster from the isolated
network to the production network then swing the IP phones and gateways over
per site.

CUCM does not initiate connections to MGCP gateways or UCCX.   The software
media resources and other services on the server may try to register with
other nodes in the cluster however.   Your best bet is to isolate the new
server from the production ones.

I am getting ready to upgrade our system from CUCM 6.1 and UCCX 5.0 to CUCM
8.03aSU1 and UCCX 8.0(2)SU2. I have some extra hardware that is supported so
I am going to do a backup then restore on a free server and then swing the
phones over to the upgraded cluster with a different IP address. If I bring
up this upgraded server with a different IP address but it will be able to
talk to the MGCP gateways and the current UCCX box. Will the call manager
try and connect to the gateways / UCCX server even if those applications are
not configured to talk to the new server?
