I switched from a Windows to a Mac. Running iTunes, not Apple Music.
I made a copy of the iTunes Library.itl file into a new drive location. It's a network storage.
On the new Mac running iTunes (not Apple Music), I opened a new library.itl file which is now stored on a network storage. iTunes took care of the music path locations. Changed the drive from A:/ (Windows format) to /Volume/iTunes/ (Mac format). I did NOT use the iTunes Consolidate option and keep "iTunes Media Folder organized" option in iTunes is unchecked.
I had made a copy of rekordbox library by going to File>Library>Backup Library on Windows.
On the new Mac, iTunes works and reads my music files and playlists are fine.
I open rekordbox and go to File>Library>Restore Library. It does it's thing. Once done, I see my iTunes playlists and I can play the files, but I'm missing rekordbox analyzed data and queue points for iTunes PLAYLISTS only. The Collection in rekordbox has all the data and queue points.
