I just purchased the V2 upgrade mainly to do my LBZ diesel, I am not going to transfer any licenses off the old V1 cable (about 10 used on there) and I was wondering since I will still use the V1 for BB logging for now if I can still purchase licenses for it. I'm not sure if once you use the SN to upgrade to V2 if that stops you from buying V1 licenses for it or not.
