How to handle multiple installed instances

I want to downpatch to v2025.05.3.0. The installation guide says to extract the zip in a tModLoader folder next to my Terraria local files, but I already have a tModLoader folder. Should I replace it, replace its content, create a second folder, or something else? I want to be able to easily return to the current patch once a particular mod is updated. I'm on steam, here's my current folder setup if that helps (I am playing through steam)

If there's a way to do it through betas on steam that'd be a lot easier, I just don't see the version I want as an option on there nvm, I renamed my current folder to tModLoader(Current patch) and unzipped the old patch into my steamapps folder, all seems to have worked fine
