The Cisco docs are fairly straightforward. I changed the IP's of our
3.1(4b) CM pub & sub, all gateways, and phones about six months ago.
Relatively painless. I used a network IDS to monitor traffic that was
being sent to the old IP's to ensure that everything was working. Oddly,
the CM boxes were trying to communicate with *each other* via their old
IP's. After checking hosts, LMHOSTS, DNS, etc., it turned out that there
was a tiny legacy service that's still part of our version of CM that
actually stored the IP addresses in the registry, and those didn't get
changed during the upgrade. As I recall, the service wasn't actually
doing anything though.
