I'm guessing you "consolidated" the library to the new location. If so this technique should let you connect a working of your library from before the migration.
Empty/corrupt library after upgrade/crashHopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the
Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and
copy it into the iTunes folder. Rename
iTunes Library.itl as
iTunes Library (Corrupt).itl and then rename the restored file as
iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!

An alternative approach would be to repair the broken links with my FindTracks script.
