Commercial beekeeps I know take bees from a weak hive in a hive body and sit it on top of another stronger hive with newspaper in between. Theory is they get used to the new queen's pheremones in the time before they get through the paper. A few small knife cuts through the paper are supposed to help the bees get started on an opening. Then they do a pretty good job of removing all the paper. I've done this once and it worked.
