Wordpres, Server -> New server move.

Right now I have a clients site on my local testing server, it has a TON of images that have been uploaded to the pages of the site. I attempted to move it to the production server (all the paths are different) …. and well nothing works, the images are still looking at the wrong paths. Whats the best way I can correct all the paths so that they reflect the new server paths? eg /home/user/public_html/wp-content/uploads should now be /home/username/public_html/wp-content/uploads …..
