I am not sure what you are saying.....but if what you are saying is : "If I wish to move to all mediums and currently have a deep brood chamber, what is the best way to do it, put a queen excluder between the deep and the medium, allow enough time for all brood to hatch and shake them into the medium, and then just simply retire the deep after I empty it?" then I would say ya, thats a ok plan, I suppose. though the bees will backfill the deep with honey.
