Sometimes you need to only move blog posts from one site to a new one.
Using the built-in WordPress features works great except for if you are only moving the blog posts it won’t bring the featured images over to the new site.
The simple solution is this plugin. https://wordpress.org/plugins/export-media-with-selected-content/
- Download and activate the plugin.
- Then use the built-in export feature under Tools > Export.
- Select “Posts” and check the box at the bottom that says “Export media with selected content”
- Upload the file created to your new WordPress site under Tools > Import > WordPress > Run Importer.
- Select the appropriate Authors or create new ones. Make sure to select download and import media.
If you have hundreds of blogs you may want to break them up into smaller batches so you don’t run into issues.
