Hello I hope this is the correct form to post a question. Here goes:

So I upgraded to Catalina and I found out that Band in a Box didn't work. So I just purchased the 64 bit version and now I'm up and running. My question is on my old version of Band in a Box Everything pack has way more Artist Performance Sets, Real Tracks and MIDI SuperTracks - Demos can I just copy them to the respective new version folders and will they work?

Thanks,
Steve

Hello Steve,

You should install Band-in-a-Box 2019 over your existing (older) Band-in-a-Box version. All of the content you have with the previous Band-in-a-Box package (i.e. RealTracks, styles, etc.) will work with the new version.

To answer your specific question though, it would also work to copy content from your older hard drive. After doing so you might want to run the Band-in-a-Box 2019 installer again, in case there are newer versions of some files.
