What Mickey Mouse school gave you an ATC licence?
Class 'B' & 'C' - you can climb the VFR to the level the IFR previously occupied when you know the level has been vacated - either by report or by 400ft on mode 'C'
Class 'D' - 'G' Which part of "You don't separate VFR from IFR" do you not understand?
