I think my best and safest answer would be, Maybe. Or, It Depends.

There are three possible approaches I could take in your situation.

One, I always save the installer .EXE files for every add-on. That way, if I ever had to reinstall BIAB from scratch, for example after a hard drive crash, I would install the main program and then run each of those other installers. The nice thing about the installers is they will not overwrite a newer file, and if you already have files installed, the installers seem to run more quickly. Now, if you did not save those installers, the program may have saved them for you. They would be located here: C://bb/Data/Installers Finally, if you do not find them, but you purchased your BIAB from PG Music and registered your serial numbers, then PG Music has an account (not the forum account; a customer account) that will have all those installers.

Two, let's assume for some reason my first suggestion doesn't work. Then I would plug in both audiophile drives, the 2023 and the 2024, and copy all the files in /bb from the 2023 drive to the 2024 drive using a file manager that will only overwrite older files. That way, I get all my bonus files from 2023 onto 2024, because they won't exist on 2024. I use a program for this called Total Commander. It's an improvement on the old Norton Commander, and it's free if you don't mind the reminder splash screen. This is going to take several hours; let it run overnight after you reply to the first prompt to overwrite only older files. I don't know your level of confidence with moving files around. I taught this stuff so I'm good, but I'm hesitant to tell others what to do. If you would like, post the steps that you are ABOUT to do as you understand them, and we can review them first.

Three, you can always call or chat with PG Music, and let them guide you. Click on the Support tab, above.
