Replace Pro with Ultimate and move Pro to different box

Getting a free OEM W7 Ultimate x64 from work.
I installed OEM Pro on my primary machine about a month ago.
How can I replace/upgrade from Pro to Ultimate on the primary machine & use the Pro OEM key on a secondary machine now or down the road?
