Once you've imported your podcast to Omny Studio, you can easily migrate to Omny Studio without losing your existing subscribers. All you need to do is tell Apple Podcasts and the other podcast directories and apps to pull from your new RSS feeds. This is done by applying a re-direct from your old feed to your new feed.
To move from Blubrry
1 - Once your episodes are saved on Omny, you can redirect your Blubrry's old RSS Feed. First, go to your show in Omny and copy your RSS feed under your playlist details.
2 - Now, go back to Blubrry’s Dashboard and click “Podcast Settings” under the Podcast Feed section.
3 - Finally, scroll the page until you get to the “Feed Settings” section. You can paste the Omny Studio Feed in the “Alternative Feed URL” field and save.
Note: Although iTunes will normally pick up on changes within a few days, you should leave the old feed in place for a couple of weeks to ensure all subscribers are moved across.
