An epic/story can be delegated to another circle. Please see Delegate to another Circle for more details about delegation.
Some of the epic/story information may differ depending on whether the epic/story is opened in the circle “delegated from” or the circle “delegated to”. This is e.g. the case for value estimates and release planning.
If you have delegated a story to another circle, you can see the release planning and estimation info from the view of the circle delegated to. It may differ from the release planning in the current circle.
