I'm removing Dynamic Chart. It uses flash and isn't really relative. At some point I'll readdress it by adding a modern charting engine.
You should be using a blank Configuration. Don't create one at all and Dremweaver will create a new blank one. If you had done that then Dynamic Chart wouldn't be an option.
You can test the Database Pages wizard and test updating old pages from MySQL to MySQLi. You should be able to open old server behaviors and update the connection from MySQL to MySQLi and the page will be updated with the new code.
Even the old standard RS server behaviors should create the correct code when using a MySQLi connection.
