It’s been a while when I last played music. Had to raise few children in a meantime Now I’m planning to start DJ’ing again. My last equipment was Denon MC6000MK2 and old MacBookPro 2010 with ElCapitan and Traktor Pro 2. Now bought MacBookPro2018 with Big Sur. Planning to upgrade to Traktor Pro 3 but controller remains the same. My questions are:
- what is the latest MC6000MK2 firmware which works with Big Sur and Traktor Pro 3?
- is there any important issues I have to know regarding download to new Mac? Any suggestions?
- is it wise to export Traktor 2 from old Mac to new and then upgrade to Traktor 3 or download the whole new Traktor 3 to new Mac and export only track collection from old Mac?
- in what order it's recommended to do the data delivery between two mac's?
I apologize my inexperience but it's been a while and now trying to get on the rails again

Thanks in advance
