That describes the transposition for B-flat clarinet, yes. For the A clarinet, D minor becomes F minor, G major becomes B-flat major. If you want to think about it in terms of key signatures, the B-flat clarinet part will have 2 more sharps than the flute and oboe parts, so if you are writing in a sharp key to begin with the B-flat player will have to contend with even more sharps. Going from the B-flat to the A instrument adds 5 flats. So D major concert (2 sharps) is E major (4 sharps) for B-flat Cl. and F major (1 flat) for the A Cl. Isn't that fun?
