ok, just thought of this.. when I copy/move the files (WP.PHP folders and file) to the new sub domain wp directory.. Cant I just NOT replace the wp-config.php so I don't have fix it them?
ok I logged into the phpMyAdmin found the primary database (Master) see a export button, it default to sql. but it shows two items in the box to export. information_schema and the database (it has a name like: mi273627382) at the buttom is a save as checkbox and default name like _SERVER_ and a "Go!" button
