Patience. Honestly I think that the best policy concerning new hives is to let the bees do what they want, unless it involves absconding, cross comb, etc. But I doubt that you speed up comb building by moving frames much. The end frames you can speed up by moving them in, but not total comb amounts.
For that you have to feed and be patient. You could take one of your honey frames from the first box and move it up to the second to try to speed them moving up, but I think that they don't build comb unless they need it and just by moving frames you don't change that.
