+WARNING:
+The upgrade is irreversible. After it's done, manual iteration cadences cannot be created.
 
-Each scenario can be a third-level heading, e.g. `### Getting error message X`.
-If you have none to add when creating a doc, leave this section in place
-but commented out to help encourage others to add to it in the future. -->
+When you **enable** the iteration cadences feature, all iterations are added
