best practice for changing hostname????
I need to change the hostname of our live ZCS 4.5.6 NE (please don't ask why)....
I've been reading the forum and wiki and I played around with the zmsetservername. So far I haven't found a procedure that I would trust enough to apply on our live server. (I can bring down the server for a while to do this)
All users in all domains use the webmail.mydomain.tld for imap/pop/web + full email as username. I have to change this into webmail.newdomain.tld
