Moving Bootcamp to new Macbook Pro
I believe that this is a problem with Windows as opposed to Boot Camp.  Windows, if I remember correctly looks for the serial numbers and unique identifiers when it starts up and has a conniption if they're not what it's expecting.  I ran into this a few years ago when I had the logic board replaced on my iMac.  I think your best bet might be to reinstall Windows on your new machine and migrate your data and settings over within Windows (that might also help Windows by giving a fresh, healthy install).
