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

[Lelio Fulgenzi]

Ok. I posted the wrong link. This is what i was using. 


http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/install/9_1_1/ipchange/ipchg911.html 


There is no updated document for version 9.1(2)x 


I ended up doing things in stages, changing IP address first, then hostname, modifying the DNS as required at each step. That's gone OK, but there were a few errors in the document, one I'm not sure how to fix. 


The first error, indicated to change the gateway separately from the IP address, where it's really one step. 


The second error, is how it's asking to perform "utils dbreplication dropadmin db " but that's not a recognized command in v9.1(2)SU1 CLI. 


Also, for some reason, under System > Cisco Unified CM, the old name still appears. I'm not sure if the dbreplication command would fix this?

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?
