You would run the Win7 Pro installer from your Premium desktop and do an Upgrade install which upgrades to Pro but keeps all of your programs, files and settings in place - only re-activation is required. Just insert your pro key when prompted and later activate at the Computer>Properties activation link.
Your Home Premium key is then available to reinstall on another machine.
*I do not know about Anytimes but thought they had to be purchased from MS directly, and OP says he is purchasing student deal. Wouldn't that be a different license?
