Langstroth to Warré conversion

The recommended solution is to acclimate the bees to the new hive by putting a 'converter' between the Langstroth nuc and the top of the Warré hive. In 10 days, create a bee 'funnel' and shake the bees out of the Langstroth nuc into the Warré hive and then take the Langstroth frames, cut them in half and attach them to the Warré top bars. Easy peasy... except I'm wondering if I shake the bees, will they get pissed off?
