Windows on Macbook Pro and iMac

[MikeM87]

Hi,

I've just recently purchased an iMac and am wondering if their is anyway i can install the same copy of Windows 7 on this that i also installed on my MacBook Pro. It is only a 1 user license as far as i am aware but i was wondering if their was a way of transfering the licenses between machines, maybe migrating them from one to another?

Thanks for any advice
