All exchanges are running 2.0 as far as we can ascertain, so no need to worry there. The wallet on mcxNOW is running 2.0, so you should be able to withdraw your coins held there. If you're having issues withdrawing your coins, please contact RS about that as its beyond our control.

When you say a date, do you mean when does the transition period finish? It will be the 20th August 2014.
