I don’t know if you’ve noticed but an update for Linux based servers is on the way; in beta now as i understand.
The biggie with this is migrating from Mono to .Net FW for Roon Server.
This might be what you’re looking for if you’re comfy with Linux in general?

I do not recommend keeping EXT4 on your drives in case you do move to Win though. It seems you’ll be in the hands of dubious creators of compatibility software which i’d not trust anyways.
Not calllingParagon “dubious”, but you would still be on a sketchy path…
