    Change author attribution on all posts

    use phpmyadmin with the following commands to modify your WordPress database, don’t forget to create a backup before running any command throught phpmyadmin.

    The first thing to do is getting the IDs of WordPress users. Once logged in phpmyadmin, insert the following SQL command:

    SELECT ID, display_name FROM wp_users;

    Right now, phpmyadmin displayed a list of WordPress users associated with their IDs. Let’s say that NEW_AUTHOR_ID is the ID of the “new” author, and OLD_AUTHOR_ID is the old author ID.

    UPDATE wp_posts SET post_author=NEW_AUTHOR_ID WHERE post_author=OLD_AUTHOR_ID;
