Windows 7 Ultimate retail to Ultimate OEM

I am building a system and put windows 7 ultimate retail on it, but have not activated it yet. The computer is running perfect and i have already installed all drivers, software, etc...

Can i somehow use the Ultimate OEM instead of retail without a clean install?

Probably not needed to know but both are x64.

You have an OEM ( system builder ) product key as well as a Retail product key?

Should be fine to just enter the system builder key.
