Moving iTunes library from C: to D: drive with ratings, playlists, etc

I bought a new computer and was able to migrate my library from old computer to new computer just fine. However, new computer has a 500GB C: drive and a 1.0TB D: drive, so I needed to migrate my 113GB music library to the D: drive. I copied the entire iTunes folder and moved it to a new folder I named Music on my D: drive. Seems to have worked fine, but I no longer see playlists, ratings, play counts, etc. Would be a nightmare to have to start over with all of that. I see the following three files did come over with the library: "iTunes Library Extras.itdb", "iTunes Library Genius.itdb" and "iTunes Library.itl".

I looked around for a simple fix but couldn't find one. Anyone know how I can fix this issue? I still have the music library on my C: drive at this time as well.
