Hi Alexandr,

This change is not supported in CCM Versions prior to CCM 6.1(2);

Note: It is not supported to change the hostname on the Cisco CallManager server because the Structured Query Language (SQL) database does not support the hostname change. This is because SQL uses the server name for many of the tables related to Cisco CallManager and exchanges this information as such with the operating system. When SQL server is installed, it binds the database to both the machine and Cisco CallManager server names. If this is changed, the database does not replicate properly since the new Cisco CallManager or machine name is not updated correctly by SQL. **If a hostname change is inevitable, then the entire Cisco CallManager must be rebuilt.

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 hostname. Also, be aware that a DRS backup that you take from a server with a particular hostname cannot be restored on a server (either a publisher or subscriber node) with a different hostname, even after you reinstall that node.

Hope this helps!
