changing ip address of cucm, unity, presence

[SJ SJ]

What is the impact and procedure for changing the ip address's of cucm 10.5, presence 10.5, unity connection 10.5 where presence and unity are already integrated with CUCM ?

How to change IP addresses has been asked plenty of times before on CSC, a search would have provided you with the answer. Or simply search cisco.com for change/changing IP + < product >

Please search for answers before posting

As for the impact, if you're using IPs for any of your configurations, you'll have to change them, is SIP trunk, services, etc.

Hi

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/upgrade/guide/10xcucrugx/10xcucrug050.html#sthash.9r8zyP4B.dpuf

does not work.

Btw, the documentation at

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/install_upgrade/guide/10xcuciumgx/10xcuciumg050.html#pgfId-745726

says you have to do it via GUI. We are going to change the IP address to a totally different subnet and that there will not be network access for the intial setup, we will only have the console access. Is there any CLI Commands which will be able to do that for Unity Connection?

For CUCM and IMP set network hostname seems to do the trick fairly easily, but is this command applicable for CUC ? We are going to move a server hosting CUCM, CUC and IMP running at v10.5.

Thanks.
