Enter the following SQL query:

  1. UPDATE wp_options SET option_value = replace(option_value, ‘oldurl.com’, ‘newurl.com’) WHERE option_name = ‘home’ OR option_name = ‘siteurl’;UPDATE wp_posts SET guid = replace(guid, ‘oldurl.com’,‘newurl.com’);UPDATE wp_posts SET post_content = replace(post_content, ‘oldurl.com’, ‘newurl.com’);
  2. UPDATE wp_postmeta SET meta_value = replace(meta_value,‘oldurl.com’,‘newurl.com’);

Replace oldurl.com with your current WordPress address and newurl.com with your new WordPress address.

Your table prefix might not be wp_. See the correct table prefix on the left panel of phpMyAdmin, and update the SQL query.
