Migrating multisite site breaks image links

I've moved a WP Multisite site to another WP Multisite and many of the image links are broken. http://www.hrnerr.org/hudson-river-sustainable-shorelines/demonstration-site-network is an example of a page the destination site that is missing pages. One thing I've noticed is the images on the page (above) references the old site. The other notable point is the uploads (files) exist here on the new site:


While the same files exist here on the old site:


Is the permalink (.htacess rewrites) messed up, the media upload folder path, or maybe the recent upgrade to WP 3.7 has something to do with the broken image links.

Also, I migrated via a simple WordPress Export/Import and manually moving the theme files over to the new server.

Thanks for any help!
