Problems moving from iTunes to Music

Hello everyone,

i have recently purchased a new mac mini to replace my older 24 inches imac and I’m troubleshooting with my old itunes library that i can’t be able to move into Music. I didn’t use the migration tool just for my personal choice so I have found the itl library file to put on Music when start the application but althought the app accept the old library to start it looks like trying charging the old library but no results appear only a circular progress bar. Someone can please help me in this migration?

thanks
