[cisco-voip] changing IP address and hostname of publisher at same time?

[Lelio Fulgenzi]

So, I'm following this document: 


http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/install/9_0_1/ipchange/CUCM_BK_C936116C_00_changing-ipaddress-hostname-cucm-90.html 


but I'm getting an error part way through. I think I know why, but just want to be sure if there's a particular way I should be doing something. 


I want to change both the IP address and hostname of the publisher that I'm rebuilding off-line. 



When I follow the instructions to change the IP address, it says there is a DNS mismatch. That's true, cause the hostname is still attached to the old IP address. 


Do I need to do this in stages? First update the DNS so that the existing hostname has the new IP address, then change IP, then change the hostname to the new hostname with the new IP address? 


I'm going from: 


host101.x.y 192.168.1.101 


to 


host95.x.y 192.168.1.95 


Thoughts?
