I recently copied C:\bb to E:\bb without issue (except it took a long time).
After the copy was completed successfully, I then deleted C:\bb.
I set the existing desktop shortcut to run the program from the new drive.
I checked Options > Preferences > RealTracks and RealDrums to make sure the folders were pointing to the new drive location.
I didn't find any other issues. Everything just worked in my experience.
