You can move your Blubrry podcast over to Podbean in one step. 

After you create a Podbean account, simply go to “Publish” in your Podbean dashboard and click on “Import RSS”. You will enter your old feed url there and the tool will automatically begin migrating your podcasts (titles and text will migrate immediately, audio and video files will take about 15-30 minutes to load).

Moreover, submit your Podbean feed to iTunes and make an announcement on your previous podcast site to notify your subscribers of your move to Podbean, with the new feed url so that they can re-subscribe to your Podbean podcast feed on your Podbean site or in iTunes. If possible, you should leave your old account active for at least a month, to help ensure the information gets to most of your users.
