Changing CUCM Host Names From IP Address to FQDN

[rajeshpat]

Hi guys,

We are planning to change the CUCM host name from IP address to the FQDN in GUI. So I have checked in the CLI the DNS entries which are looking good, checked the FDQN to IP resolving which is good and db replication also good. Now I want to know after changing the IP to FQDN what are the post activity which I have to do like service restart, certificate re-generating or server reboot. please advice me on this.

The important thing to confirm is that your devices, i.e. phones need to resolve the FQDN now, so make sure that the phons get proper DNS server from their DHCP scope.
