Please note that whenever you are redirecting/importing an RSS feed, your historical analytics will not be available in the new program. Please download your historical analytics to CSV to maintain an archive.
To migrate a playlist within a program to another playlist within a program, you can take these steps:
1) Create a blank playlist in the new program to import into (just needs placeholder name and category because this will be updated)
2) Import into that playlist using the RSS feed. There's an RSS importer for the playlist at this dropdown here:
3) Make sure the 'update playlist details from podcast' checkbox is ticked.
4) Once the import is complete, you can take the re-direct steps which are outlined in this help doc.
One other consideration is that if you have ads running from the ad-server currently then you'll need to switch them off for the program so that they're not imported with the audio. You can do that here:
Please note that Spotify behaves differently to most other podcast apps and will not start downloading from your new RSS feed for old episodes until the original episodes are unavailable.
This means that you will continue to see downloads of old episodes in the account you've migrated from until you delete the original episodes.
Please don't delete your old program/account until the redirect has been in place for at least a week to ensure all subscribers on other apps are moved across.
Please contact support if you need clarification.
