# Change the hostname of your server

If the hostname of the new machine serving P4 Server is different from that of its predecessor, your users must change their `P4PORT` settings. If the old machine is being retired or renamed, consider setting an alias for the new machine to match that of the old machine, so that your users won’t have to change their `P4PORT` settings.
