If you have the latest version of databridge, then you can just create a mysqli connection and open up each of your recordsets, insert, update, and delete server behaviors on the page and change them to the new connection. Once the connection is changed the extension will update all of the other code on the page to mysqli as well. You still have to do it page by page, but it goes pretty quickly as long as you don't have a lot of hand edits to begin with.
