Duplicate iTunes library in Catalina

[semente]

Happy High Sierra user here, I wonder if the new Music works in an identical fashion to iTunes.

 

If you haven't already backed up your music files to an external drive (which you should have) now's the time to do it!!!

• Hold down the Option key, then open the Music app.
• In the window that appears, click Choose Library.
• Select a library (your old iTunes library), then click Choose.

 

If/when your iTunes library folder opens check which files are missing and import them to your library.

Quit Music. Restart the computer. Run Music.

If everything is working and all files are present it is probably safe to delete the other (Music) libraries.

 

Alternatively you can delete all your music from the computer and all the libraries (back up first!!!).

When you run Music it should create a new library then you can import all the music from the external drive (you'll lose playlists and ratings).
