Another question for an answer I should already know by now:

I have my old V4 characters saved in the now old .daz file format and if I remember correctly, DS 4.5 was the last version to recognize those file extensions and anything beyond that needed to be converted to .duf? So 4.8 won't recognize the old files?

So do I need to upgrade from 4.03 to 4.5, convert my V4, hair, clothes, props, and everything else from Daz scene to .Duf before I can then upgrade to 4.8 and reinstall everything all over again into that program?
