[cisco-voip] building a new cluster from DMA (getting from point A to point B)

I'm going through building a new cluster that I'd like to run concurrently on my network with new IP addresses and CallManager names. I have always used IP addresses and would like to continue using IP addresses for now. I've installed 7.1(3a) along with a DMA import. Then I applied 7.1(5) upgrade. No problems. I did this all in an isolated switch with only the publisher and FTP server. 

Can I just go into the servers, change the IP address, then go into the CallManagers and change the names? Is it that simple? That way I wouldn't have to bother messing around with CallPark numbers and CallManager groups. If simply changing them is the answer should I change one first? 

Once I confirm there is no communications happening from the new publisher to the old cluster (via wireshark) I can then plug in the publisher into the network and start installing new subscribers. 

This is what I have now: 

publisher hostname: iptccm105 
publisher ip addr: 10.104.91.105 

(during the install, the process asked me about changing the ip address, but i can't recall if it asked me about changing the name, but i think it did) 

The old/new information is below. 



Servers: 

10.104.20.101 (OLD) -> 10.104.91.104 (NEW) 
10.104.20.103 (OLD) -> 10.104.91.103 (NEW) 
10.104.91.105 (no change) 
10.104.96.104 (OLD) -> 10.104 .91.204 (NEW) 
10.104.96.106 (OLD) -> 10.104.91.205 (NEW) 
10.104.96.108 (OLD) -> 10.104.91.203 (NEW) 

CallManagers: 
uogccm101 (pointing to 10.104.20.101) -> iptccm104 (pointing to 10.104.91.104) 
uogccm103 (pointing to 10.104.20.103) -> iptccm103 (pointing to 10.104.91.103) 
uogccm104 (pointing to 10.104.96.104) -> iptccm204 (pointing to 10.104.91.204) 
uogccm105 (pointing to 10.104.91.105) -> iptccm105 (pointing to 10.104.91.105) 
uogccm106 (pointing to 10.104.96.106) -> iptccm205 (pointing to 10.104.91.205) 
uogccm108 (pointing to 10.104.96.108) -> iptccm203 (pointing to 10.104.91.203)
