Migrating License Manager to New Server - handling existing clients

We are looking to migrate our SW2010 license manager to a new server.  I think I understand the concept of releasing the license back to Solidworks and re-activating it on the new server, but I was wondering if there was a way to automate how the clients will handle the switch.  I know most of them are configured to use a dns name (i.e. 27654@server) but the new server will have a different name.  Is there a way to automate the change, or will the users have to each change their configuration - and how would they do so?

Thanks!
