Upgrade from 2007 to 2012 and migration to new server

Hi

I am trying to plan out the proper path to move SolidWorks to new hardware and upgrade it from 2007 to 2012 at the same time.  This is of course if I am not mistaken and the 2010 version that they told me was on the old server isn't hiding some place since I only found 2007 SP0.0.  Any help you could provide would be great as I am being tossed into this and would rather not mess it up.

Thanks
