Hi

Google this:

change ip address cucm 8.6

With your version for specific guidance...

Hi Harrison,

Thanks for your reply.

In the meantime I've tried to change the IP address from the cli. but an error is generating which I've attached for your better understanding.

Please instruct me.

I'm waiting for your reply.

Hi Nizam,

This looks to be an issue with the DNS server configuration, please ensure that cucm server info is setup correctly there.

Hi Manish,

Thanks for your reply.

It would helpful for me if you explain.

It is noted that, I've added a new host-name in the DNS of Domain Controller to avoid conflict with the existing host-name. After that while I try to change IP add by cli then the error has been arisen.

Hi

Did you change the IP address without first changing it in CCMAdmin system/servers menu?

Do you have subscriber servers?

Hi Harrison,

Yes I tried to change the IP add without first changing it in CCMAdmin system/servers menu. Should I first change the IP address from CCMAdmin system/servers menu?

Is it the only reason for this type pf error?

Hi 

The procedure is documented for a reason. There are steps you go through make and validate the change, which you have skipped. 

I would restore your backup and start again.

Hmm... let me google that for you again:

Hi Harrison,

Thanks for sharing the link. I could already changed the IP address but another problem has been raised.

While I going to login to cucm an error is prompted is "Database communication error"

What should I do now?

Post up 'utils service list' output from the server.

Did you restore and go through the process again? I'm guessing you did not.
