Hi,

The domain name change would require

a. regeneration of certificates

b. restart of servers in a cluster

c. CLI command is set network domain acme2.c1

when u run the command from putty, u would get the message as below

admin:set network domain acme2.c1
          ***   W A R N I N G   ***
Adding/deleting or changing domain name on this server will break
database replication. Once you have completed domain modification
on all systems that you intend to modify, please reboot all the
servers in the cluster. This will ensure that replication keeps
working correctly. After the servers have rebooted, please
confirm that there are no issues reported on the Cisco Unified
Reporting report for Database Replication.

The server will now be rebooted. Do you wish to continue.

Security Warning : This operation will regenerate
       all CUCM Certificates including any third party
       signed Certificates that have been uploaded.

Continue (y/n)?y

trying to restart system...

regds,

OK, and what happens with the license? It are lost?

No, PLM licenses are not tied to domain name/hostname, they're tied to the MAC address from the server.
