Just a quick update. Since Totara 2.x, the replace script is now located @ yourdomain.com/admin/tool/replace/index.php.

On a related note, the current script only supports MySQL and PostgreSQL databases. Does anyone have a comparable script for MSSQL? Moodle tracker tells me this is on the radar for Moodle 2.3.x, so Totara may not inherit that enhancement until Easter 2013.
