Moving iTunes from Leopard to Mountain Lion

I got a new iMac and attempted to move my iTunes files manually from my old G5 by swapping the following items:

/Home/Library/Music/iTunes

/Home/Library/iTunes

/Home/Library/Preferences/com.apple.iApps.plist

/Home/Library/Preferences/com.apple.iTunes.eq.plist

/Home/Library/Preferences/com.apple.iTunes.plist

/Home/Library/Preferences/com.apple.iTunesHelper.plist

When launched my new iTunes it was missing a good number of playlists and files.

I then tried using the Apple Migration tool. It succesfully copied all my files and playlists that worked fine, but was set up under a new User identity.

When I again moved the files from that User to my current one I got the same missing results as before?

Is there some file I've overlooked? Some step I'm missing?

Thanks,
