Upgrading to WP 5+ with block content - Export & Import Page Content
I'm upgrading a pre-Wordpress 5.0 site to the latest WP version using blocks. I created a staging site and went through all the pages/posts and converted the content into blocks. Now I need to export ONLY the page/post content (+ custom fields) and import it into production without effecting anything else.
I've tried the default WP import/export tool but this does not appear to work on existing pages that are already on production.
I found this topic often when I Googled it but nothing that offers a solution for me.
What are my options?
