I'm looking to change the hostname of our Callmanager because of a change in the naming convention for all our servers.
Is it as easy as it seems or are there any precautions I need to be aware of?
My thoughts were to just Change hostname under Cisco Unified CM Configuration for both PUB and SUB
Since I use mostly IP address for most of my configuration, are there anything else I need to be concerned about?
Also, how do I generate a new SSL cert based on this change so admins and users won't get a certificate mismatch prompt?
***Note Prior to Cisco Unified Communications Manager Release 6.1(2), you cannot change the host name of either the publisher node or subscriber node after it is installed. If you must apply a new host name to a server, you can delete the server from Cisco Unified Communications Manager Administration (System > Server) and then reinstall the server with a new host name.

Hope this helps!
