Loading Battery 3 kits with Battery 4

Hi folks,

I have a ton of logic pro x projects on my 2012 intel macbook (running Catalina) that use Battery 3 and I'm trying to put together an upgrade path because that machine is on its last legs. My plan is to buy Battery 4, put it on my M1 Mac Air, and then move my logic projects over (and also, of course my samples, using the same directory structure so Battery will know where to find the content). I watched some videos that seemed to indicate that Batt 4 will load 3 kits, but I just want to see if anyone sees any issues with this working before I spend the money on Batt4. Thanks very much.
