FWIIW I think this is the thread that describes converting Genesis to native Poser:

However I am not sure this is still necessary. You could just try loading V6 then saving as a new character.

For me V6 works well in Poser 2014. If load a clothing item to V6 then 'Transfer Active Morphs' seems to do a fine job in fitting. Also the morph brush rocks for any final fiddling.

I have all the DSON stuff in a separate folder. DSON does not seem to interfere with anything else.
