Wordpress Dispersing Multisites

I have plus 15 sites locked in a Wordpress multisite installation by a previous developer, the owner of the company decided that it would be in the best interests to break these up and segregate them to different servers. I am having issues trying to do this with plugin data not following.

Is there a better way to do this?

My attempts so far are outlined like this.

• I attempted to log in to one site and export it's XML then merge it and the theme into a new installation. This allowed the site to carry over, but I lost all the data for plugins and users.

• I dumped the entire database for the MU install, then tried to kern out all irrelevant tables and files. This achieved what I wanted, but left around a lot of bad table structures, and many files that aren't in use making it overly cluttered and slow.

• Recreate each site by hand. This also works, but adds weeks to creating each site individually.

My database structure weighs in at around 49.8mb and looks like this at the moment.

*DB: multisite  (200)

I'm curious if I remove wp_ulc_ from the head of all tables (wp_13 being the exception), and replace all instances of wp_ulc_ inside the tables, delete all tables except one site at a time, and load those on top of a fresh install if I will be able to keep plugin data and users? This is extremely confusing to untangle and I'm not sure the best way to proceed in separating each site from the MU install. Advice would be (extremely) appreciated.

From your description, combine the best parts of #1 and #2. Import the previous site's XML/theme, and do a SQL INSERT for all data in your 'users'/'plugin' WordPress Tables.

There might also be already-developed tool to clean out old versions of posts and other WP content that are filling your databases.
