To retain all the playlist, podcast status, apps, and media organization in your iTunes setup do the following:

1. Install iTunes.
2. Make sure iTunes is not running.
3. Copy all the media files from your old machine to the new. If all the media is in the standard iTunes location, copy to the entire iTunes directory.
   

   XP:	C:\Documents and Settings\username\My Documents\My Music\iTunes
   Win7:	C:\Users\username\Music\iTunes
   OSX:	/Users/username/Music/iTunes In Finder, navigate to Home Directory, Music, iTunes.

4. Copy any media outside the iTunes area to their same paths on the new machine.
5. Start iTunes and let it rebuild its database.

If you are using iTunes to sync your contacts and other personal information with your iPod’s or iPhone’s, then be sure that the application that holds the personal data is installed and up to date before syncing the device.
