Delete the server from the UI.. and then add a new one. That is all you will need to do.
Just make sure to configure which NETWORK port that is it supposed to listen to.
I doubt you did ANY tuning to the advanced settings, so nothing to worry about. If you did then make sure you document tham and duplicate it on the new server.
You can also just update the IP or name that the server is pointing to.. just make sure you have instaleld the SW on the new server. Once you restart it will then work.
