Syncing Apple Music with MP3s on a new external drive while retaining metadata
I have a huge library of mp3s stored on an older external hard drive. On my iMac, the Apple Music playlists are linked to those mp3 files on the older hard drive.
To avoid the catastrophe of losing everything to a failed hard drive, I have copied the entire library of mp3s from the older drive to a new external SSD drive.
My problem is that I cannot figure out how to sync Apple Music to the mp3s on the new external drive - but still retain all the metadata (playlists, ratings, comments, etc.). I have been curating my music collection in iTunes/Music for 20 years and I don't want to inadvertently lose all that metadata in the process!
FYI - I have spent two hours researching this issue but have not found a clear answer. There is a lot of info on how to migrate music files that have been copied to the computer's Media folder...but that is not the problem I am trying to solve.
Thanks for your kind assistance!
