Quite simple answer to this question: No easy solution available. The easiest and fastest solution is:

Step 1.
Make a backup of your current installation, purely for state of mind soothing reasons.

Step 2.
Install your old disks to a new folder, if you have, that is preferred, on a second computer. Then you can duplicate everything like drive, folder, and any other computer related setting. (There are some files BIAB uses to figure out where to install and find stuff. If you use a "different location" like a different drive name or folder name, unexpected behaviour could help you find some unexpected behaviour.)

Step 3.
Copy your current installation over the new installation. Overwrite any duplicate file names. You should now have all old files and all current files in a current state.

Step 4.
Test it, if it is o.k. just copy the modified current version to where your BIAB usually resides. Remember step 1, you still have a backup, if you encounter difficulties.


Best practices 1:
What I do is: I do have an external USB drive solely for backup purposes. I copy all my music files and music related software to that drive. Software is copied to that drive before I install it. This drive has no other purpose.
I do have, btw, another similar drive, that is used for regular weekly backups. So I have at least two valid backups available.

Best practices 2:
Install any new BIAB version onto your current installation -- unless PGMusic provides a different instruction.
