If you ever decided to change your WordPress site’s domain, firing up following MySQL queries can reduce internal redirections.
Assumptions:
old.comis old-domainnew.comis new-domain
Queries:
UPDATE `wp_options` SET option_value = replace(option_value, 'http://www.old.com', 'http://www.new.com') WHERE option_name = 'home' OR option_name = 'siteurl';
UPDATE `wp_posts` SET post_content = replace(post_content,'http://old.com','http://new.com');
UPDATE `wp_postmeta` SET meta_value = replace(meta_value,'http://old.com','http://new.com');
UPDATE `wp_comments` SET comment_author_url = replace(comment_author_url,'http://old.com','http://new.com');
UPDATE `wp_comments` SET comment_content = replace(comment_content,'http://old.com','http://new.com');
UPDATE `wp_commentmeta` SET meta_value = replace(meta_value,'http://old.com','http://new.com');
Above will take care of, options table, posts & comments. If you have any other database table/column which need change you can run queries like below any number of times:
UPDATE `TABLE_NAME` SET meta_value = replace(COLUMN_NAME,'http://old.com','http://new.com');
Comments
Nice outline of what needs to be changed. I guess you would have to do this if you had no choice, but I prefer to use wp-cli search-replace…. A lot less typing and it’s done with one command. There is even a –dry-run option.
