Transferring from Mac mini (Bootcamp) to Macbook Pro
I purchased a Mac mini earlier this year, and while it is an amazing machine, I think a Macbook is something I will need at the moment as I am traveling a bit. Now my issue is that I run windows via Bootcamp on my Mac mini and would still like to do so on a Macbook. How difficult is it to transfer from one to the other? I imagine that the Mountain Lion OS makes it easy to do so, but I want to make sure. I also don't want to lose the $200 that I spent on the Windows 7 key.
(I would like to mention that I am not worried about losing any data on Mountain Lion OS as everything is on some sort of cloud, same is to say for the Windows side.)
Mac mini, OS X Mountain Lion (10.8.3)
