Here is a link:  http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/install/7_1_2/ipchange/ipchg712.html

Yes.  CUCM is a real time application.  So, when you change the IP address, any existing conversation with other CUCM nodes, voicemail systems, application servers, phones, voice gateways, etc. is interrupted and needs to be re-established.  Also, when you change the IP address of a node in the cluster, you need to reboot all other nodes.

On the CUCM system itself?  Yes, all of the services are bound to the IP address.  This is why you need to reboot a CUCM node after changing the IP address.  Other CUCM nodes are affected as well.  That is why you need to reload them.  Outside of the cluster, it depends on the application.  For Unity, you need to modify UTIM.  For CUC, you need to modify the telephony integration.  For UCCX, you need to modify the JTAPI and AXL providers.  There are other examples.  Don't forget DHCP Option 150.  This is usually an IP address.

I am not sure where you are going with this, but I am sure the answer to this question is yes.  You can look at compatibility information here:

You will also want to review the installation and upgrade guides here:
