Import/Export Feed Sources
Feed Sources are stored in your WordPress site as a custom post type, making it easier for you to import and export them at will.
The process is, therefore, the same as if you were to import/export WordPress posts or pages.
Importing Feed Sources
Navigate to Tools > Import in your WordPress dashboard and choose the WordPress Importer. If you haven’t installed it yet, you will be prompted to do so. Just follow the instructions provided.
On the Import page, choose the file that you want to upload and import by clicking on Choose File, and then clicking on Upload File and Import.
The feed sources will be imported and found in RSS Aggregator > Feed Sources.
Exporting Feed Sources
To export your feed sources to a file, such as to keep backups while running some tests or to migrate them to another site, simply navigate to Tools > Export in your WordPress dashboard, choose Feed Sources and click the Download Export File button.
