If this is music you purchased from iTunes merely download all of it from the Apple Store to your new phone. If it is music you ripped to your iTunes library connect your new iPhone to the computer and sync it with the music library.

No, I am referring to the online Apple Music Store. But you could make a Genius Bar appointment and ask them to assist you. https://www.apple.com/retail/geniusbar/
