Reply to Upgrading 2 Traktor Pro 2

I have been using Traktor Scratch Pro for a couple years now and just upgraded to Traktor Pro 2. I was getting frustrated and realized that you can't upgrade from Scratch Pro to Pro 2. I was going to buy the extra upgrade to Scratch Pro 2 and I own and Audio 8, but I was wondering if anyone knows if I can use my Hercules RMX with Scratch Pro 2.
