To use the Label Engine podcast feature you will need to replace your existing podcast rss feed with the rss feed generated by Label Engine.

To do this, you will first need to upload all your existing podcast episodes to Label Engine and enter in all the data for them.
​
Once this is done, you will need to update your podcast settings on iTunes to replace the old rss feed reference with the Label Engine one.

iTunes also recommends taking the following additional steps; however, you will need to contact your existing podcast provider to implement them:

To avoid losing subscribers, you must announce the change directly to all users who are subscribed to your feed. To do so, you should:

* – Use the <itunes:new-feed-url> tag described in the iTunes RSS Tags section below.
​* – Set your web server to return an HTTP 301 redirect response when receiving a request for the old feed.

This will update the iTunes Store with the new feed URL and your subscribers will continue to receive new episodes automatically. Be sure to maintain the <itunes:new-feed-url> tag and the HTTP 301 redirect response for at least 4 weeks to ensure that most subscribers have attempted to download your most recent episode and have thereby received the new URL.
​If you need additional help, contact us (http://support.itunespodcasts.com/). Include the iTunes Store link to your podcast, which you can get by clicking the triangle next to your podcast’s Subscribe button in the iTunes Store.
