Massive mp3 file(path) move question

Question

Alright so I recently purchased a 2 terabyte network server for my home network. The purpose of this is to move all my music, movies, photos, etc. to the network drive in order to clear out all that space on my laptop's drive. At this point and time, I've only copied all my music to network drive. Figure the next step would be is to delete all my music off my local drive. But then got a little worried about iTunes. Now when I delete my music off my local drive, iTunes will be looking for the mp3s via the originated file path. Obviously the file is not going to be there. So when this happens in iTunes, the circularly enclosed exclamation point pops up and iTunes wants you to manually and find the file for it to play. So essentially my question is... Since I'm doing this on a large scale, Is there an easier way to get this done?
Best solution I was able to come up with was to delete all the songs in iTunes and re-drag all the music back in there. BUT... the problem I have with that a good majority of the music's album artwork were manually put in by me (kind of uh...yeah about seeing the album artwork on the screen when I'm listening to my iPod). So I don't want lose all that it. Help! Kind of long, I know. Appreciate any help or suggestions.

When my query looks like
