The hostname of the server on which ISPConfig is installed is permanently changing from: myhost1.mycompany.com to: myhost2.mycompany.com The hostname myhost1.mycompany is going to be used for other purposes, so it cannot be used at all. During the transition period ONLY, I have myhost2.mycompany.com as a CNAME alias to myhost1.mycompany.com. Once the change of hostname is complete, myhost2.mycompany.com will be changed to an A record with a new IP address. I went to the ISPConfig control panel > Server Config > myhost1.mycompany.com > Server and I see that the Hostname field is present. I'd like to confirm that changing this is the right thing to do and if other manual fixups are needed.
