Regarding the old server, you need to uninstall the server if you are not going to use the license anymore or downgrade it to a free version (assuming all you existing use support the edition).
That's it. Next, in your new machine install and use the license key.
By the way, usually I highly recommend Not to use the forum for LICENSE questions. It might look like we understand since we orders several dozens licenses ourselves, but I learned that this subject can be very complex and you better read the small letters and understand it 100% before you recommend someone. This is less related to a DBA or any technical person and more to administrative.
If you are in north America you can call 1-800-426-9400, Monday through Friday, 6:00 A.M. to 6:00 P.M. (Pacific Time) to speak directly to a Microsoft licensing specialist, and you can get more detail information from them.
