Moving Music/iTunes files & Library to external SD Card.

Hello,

I need to move my Apple Music/iTunes libraries to an external SD Card. Over time, I think the music has become located in a couple different directories, including:

Music/iTunes/iTunes Media/Music

Music/Music

I have tried a couple times and seem to get many corrupted D/B links between the Library and the file itself but don't know what I'm doing wrong.

I also have A LOT of Playlists I would like to transfer to the new Library.

If there is a way to consolidate all the music files into one directory without duplicates and still retain the playlists, that would be nirvana.

I am running macOS Monterey (12.7).
