Rename Root AMS management server object

Hi - we have just installed a second AMS in a DR site for a client. The original (root) AMS is listed as Server in the Management Servers list but the new server has it’s correct (network) name. How can we rename the Root server so that it is called something more helpful than “Server”.

Thanks,
Edmund

Open console of the SQL server and execute following query on avast! database:
update dbo.Object set Label = ‘hostname_here’ where Id = ‘0’;
