Rename a Client

I have read lots of questions asking partial aspects of this, but have found no question, no document explaining the whole thing.

Is it possible to rename a Networker Client?

Which is the procedure?

Use cases for this may be due to a host name change or an error on initial configuration. Suupose that I simply want to change name "server1.mynet" to "server2.mynet" in Networker 7 without losing existing backups of "server1.mynet".
