Search and replace tool
From MoodleDocs
Admins can search and replace text e.g. a URL in their Moodle database at http://yourmoodlesite.org/admin/replace.php. A database backup is recommended before running the search and replace ;-)
Note: You are currently viewing documentation for Moodle 4.0. Up-to-date documentation for the latest stable version of Moodle may be available here: Search and replace tool.
