Solution:1
Try using this plugin,
https://wordpress.org/plugins/velvet-blues-update-urls/
Update GUID’s and urls from old to new.
Solution:2
As per my knowledge, when wordpress site is migrated to other domain. By changing these two row values in database table wp_options
- select option_value from wp_options where option_name=”site_url”
- select option_value from wp_options where option_name=”home”
All rest of urls in database tables will be changed automatically, except urls in post_content column in wp_posts table.
As per your query, above method is not working.
Alternate option: https://wordpress.org/plugins/search-and-replace/
Above plugin will automatically search for given string and replaces. Make sure please take backup of your database before processing.
Caution: Do not change GUID value manually. If it so also, it doesn’t work.
