Change WF Server name

I have WF 3.2.2. In WF admin, under Server Settings, the Server name is wrong, hence are some things in Sytem Properties. SysProp items have edit buttons. How do I change the Server Name under Server Settings?

Hi,

you may edit (or add) the property xmpp.domain but if you change it there the rosters will get invalid as there the full JID’'s are stored and these will not be updated. So you could also shutdown Wildfire and replace the old name with the new name within the database.
