Import existing podcast RSS feed into Blubrry

PowerPress has an import function for existing podcast episodes:

It doesn’t have a function for ongoing updates. After you do the initial import, you’ll have to add new episodes to your site manually.

If you want to keep your current feed and use PowerPress at the same time, you will have to add your episodes manually to both when you publish a new episode. Alternatively, once you have PowerPress set up, you can implement a 301 redirect from the old feed URL to the new feed being generated by PowerPress:
