It’s pretty straightforward from here on in. From this point, you’ll have two groups of ununsed data:
1.) personal content, typically in your old ~/Documents/FXpansion directory
2.) system content, usually in /Library/Application Support/FXpansion/BFD2 and /Library/Application Support/FXpansion/BFD3
1.) is easy to deal with. Just copy all your old personal presets from the old location into the new. You’re unlikely to run into issues with that.
(note: when I say “preset”, I mean presets, kits, grooves, mixers, processed drums, swing templates (which never worked well), etc.)
2.) is a little more tedious. Some expansion packs installed content in both the BFD2 and the BFD3 directories. So, now that you have reinstalled BFD3, you potentially have four locations where content could be found.
The easiest, most straightforward way to deal with it is to just make sure that you have just the newest version in your default path (i.e. /Library/Application Support/BFD Drums directory somewhere. So anything that wasn’t installed by your content installers into BFD Drums, go ahead and copy it over from the old location.
If you have both a BFD2 and a BFD3 version of a file, delete the BFD2 version. It won’t help you to have both. If you have just the BFD2 version, go ahead and put it in /Library/Application Support/BFD Drums/BFD2. You’ll enable that with the “Add BFD2 Paths” button.
There should be at most a few BFD2 presets that don’t work after that. Those, we can open, save as a BFD3 user preset, move into your main preset directory, and delete the old BFD2 version.
Now, my expert tip on keeping the whole thing organized and free of any conflicts. I don’t keep any expansion presets in /Library/Application Support/BFD Drums, even if that’s where the installer put them. I always immediately move them over to the directory where their expansion is.
So, under BFD Horsepower, there’s the Audio directory, and I’ve added Presets and Kits, and moved those presets over there. You’re scanning that path for information anyway, so Content Locations will find them all the same. If the expansion came with Grooves, I also move those over.
