moving license from old serv to new

The server at work has seen it's best days, so we are going to swap it with
another with the same computername ip address etc. We use wies terminals
exclusively, and I need to transfer the 8 lics we have to the new server.

Is there an easy way to do this?

ps the admistrator has lost the paperwork, will the numbers in the lic
server help at all?
