It might be a case by case transfer using different techniques based on complexity of the design.
For the example all I did was import it as an image. Traced it, applied a cut path to it, and deleted the original import to leave only the cut paths. It looks good from the designer viewport.
But I am sure there are half a dozen different methods to do it. I don't have the dxf add-on but I have a feeling that is probably the way to go.
