There is no simple method. You can find many youtube videos on "chop and crop" but this only works well if you are an experienced beekeeper and you have wax comb with no wires. Plastic will foil your attempts. Wires will make a mess, in my experience, but perhaps you can figure out a way to cut wires without ripping the comb up. A shaken swarm (or package) is much less complicated...
So, yes, if you catch the queen and brush or shake all the bees into the top bar hive and give the combs back to a different hive, that is probably as good as it gets... unless they make some frames for the top bar hive, in which case you could do a cutout and rubber band the combs into the frames.
