Develop with Evaluation then sell with Commercial version?

After extensive research and decision, I start believing, GapiDraw is worth of the money. I want to develop my game on GapiDraw - Evaluation Version, and then when the game is going to go to market I will purchase commercial version and simply replace relevant DLLs.
Is this approach ok, and will there be any technical difficulties resulting from possible differences between evaluation and commercial version?
Thanks,
