Can I import Battery 3 kits to Battery 4?

My employer bought me a new Macbook M1 Pro, OS 12.1. Just now learning that Battery 3 is not compatible with OS12.1. Very bad news since B3 had so many great multi-layered world percussion and acoustic drum sounds. Are these still available for B4, and maybe I don't know how to access them? Or, can I upload them from my old computer and import them to B4? B4's sounds are so-so, IMO, most of them being 1 dimensional and not layered. It does have a better interface and I was able to integrate B3 inside of B4 on my old macbook. Hoping to do that again.

Thanks for any advice!😊
