Maker to "Normal" solidworks

I have done some work on a maker lisence of Solidworks. After grabbing an opportunity and staring my own business i changed over to normal solidworks  (as per the rules of the maker lisense). I want to know of there is a way of removing the watermark from the maker files. I have tried transitioning via a native 3D format but I am losing all the design intent. Has anyone done this?
