'Upgrading' To Full License from MSDNAA-provided Vista

I will begin using a newly built computer with a Windows Vista Business install obtained through an MSDNAA license in the near future; however, I will need to use the computer for commercial and non-academic purposes. As outlined in the license (and the summary http://msdn.microsoft.com/academic/program/usageguide/ ), I cannot work under the MSDNAA license.

Does anyone happen to know what I would need to do to get an appropriate ("full" ) license? Would a retail-bought and applied 'upgrade' package do the trick, or is there something I am misunderstanding about the whole deal (and I actually don't need a new license or I need to reinstall the whole operating system)?

Thanks!
