Wordpress database modification during migration

To setup an existing Wordpress DB into the new server we should run these minimal 2 queries to adopt all required URL changes. It is exactly changing the Site URLs from old one to new one.


update `wp_options` set `option_value` = replace(`option_value`,'<SOURCE URL>' , '<DESTINATION URL>')

update `wp_posts` set `post_content` = replace( `post_content`,'<SOURCE URL>' , '<DESTINATION URL>'),  `guid` = replace( `guid`,'<SOURCE URL>' , '<DESTINATION URL>')

Here wp may need to changed with required prefix.

We have changed only 2 tables

  • wp_options  and
  • wp_posts

 A sample Php code is available here.
Please Note:

If Page/post is using Permalink other than post/page id, e.g. Post Name, you have to go to Setting -> Permalink and re-save the settings to be effective in new site.
