Switching from PC to Mac

Hey all.
Just a quick question. I am switching from PC to Mac in a few days. Do I just install a new copy on the Mac and use my same serial key or do I need to de-register my PC copy of Cross DJ first?
Further to that is it possible to transfer collections over or do I start again from scratch?
Thanks.
