For example I have field group FG-A, setup for Page Template page-a.php
I need to change page template name to page-awesome.php
After changing that, in Custom Fields tab, field group FG-A does not apply for this template anymore, so I gotta do that manually again, and even go to check pages (with template page-awsome.php) to see if this still works.
Is there any kinda SQL query to fix this all at once, instead of manually doing this for every single field group (which this website has a lot)
For pages, this is what we did:
UPDATE wp_postmeta SET meta_value = ‘page-awesome.php’ WHERE meta_value = ‘page-a.php’;
