Domain name change - CUCM

[Kulasekararaja]

Hi Folks,

Looking for a best help here.

We are in the middle of a migration in which we have to do the domain name change on our existing CUCM cluster (3 Nodes) version 11.5.1, is there any document which can explain the procedure in detail and what are all the business impacts may happen during this course.

Thanks in advance.

Are your plans to “only” change the domain part of the FQDN of the nodes in your CM cluster or are you also planning to change the user facing part that attains to domain name?

5 seconds of google search would have answered the question for you:

And please also keep @Roger Kallberg's question in mind.
