How to manually replace the old URL in the WordPress database

All most every server has the PHPMyAdmin installed and configured. If you have the cPanel access on your hosting account, just log in and find the PHPMyAdmin and access it.

Now access the SQL tab inside the PHPMyAdmin.
You should paste the following code inside the SQL form field.
UPDATE wp_options SET option_value = replace(option_value, 'olddomain.com', 'newdomain.com') WHERE option_name = 'home' OR option_name = 'siteurl'; UPDATE wp_posts SET post_content = replace(post_content, 'olddomain.com', 'newdomain.com'); UPDATE wp_postmeta SET meta_value = replace(meta_value, 'olddomain.com', 'newdomain.com'); UPDATE wp_comments SET comment_content = replace(comment_content , 'old_domain.com', 'newdomain.com');

The results should confirm that the old URL’s are replaced inside the above-selected tables like wp_options, wp_posts, wp_postmeta and wp_comments.
