Move all stores on current marketpress to new multisite setup

I would like to move a my multisite marketpress setup on wordpress to another new multisite setup (essentially i'm redoing my site). I'm familiar with mysql database and even wordpress normal database structure, but my current database has over 4373 tables, i'm not quite sure which ones are specific to marketpress. Do you guy have any documentation or a tool to backup the sites and product information and restore it on a new instance of WP?
