Has anyone tried this, or can anyone find any information about this? I had the idea of transfering my island to my secondary Switch and starting over. But then I thought, if I end up too flustered trying to find a map that works for me, I'd like to be able to put my island back on my main switch, as my secondary has a bad battery due to being gen1. I'd hate to be tethered to my charger almost twice as much in the instance I can't transfer it back afterwards.
