I bought a new imac and purchased Final Cut Studio 3 (upgrade). I already have FC 2 (it was for my old machine). Do I need to install Final Cut 2 on the new machine and THEN upgrade to 3? Or can I just start with an install for 3 and simply enter my serial from my 2 version? I have worked with programs in the past that worked both ways.

I understand that legally should un-install the 2 version... Frankly it was about to blow up my old machine anyway -> thus the upgrade, so I have no problem with this.
