Q: How do I transfer ALL MY EXISYING PLAYLISTS and Music from iTunes 11 to the NEW iTunes 12.2 64 Bit ?

If they are on the same computer, they should not have been changed or removed by the upgrade process, other than updating the database structure to match that required by 12.2.  Some users do report, however, that this occurs when an update is installed - if this is the case for you, see turingtest2's user tip on Empty/corrupt iTunes library after upgrade/crash.

If you have an old computer running iTunes 11 and want to transfer your library to a different one, running iTunes 12.2, see How to move your iTunes library to a new computer - Apple Support.
