Managing Releases in Planner
Releases and sprints are the timeboxed iterations representing the schedule according to which development work is accomplished and which results are delivered.
Creating and Deleting Releases

Create Release or Create Sprint to create a new (sub)release. The new (sub )release will be inserted depending on your scopeIf you are in Project Scope, a new release will be created with no parent
If you are in Release Scope , a new sprint will be created as a child of the current release displayed in Planner.
If you are in Sprint Scope, a new sprint will be created as a child of the current sprint displayed in Planner
You can delete an existing (sub)release using the context menus in the left pane. If you delete a (sub)release, all of its direct and indirect children will also be deleted.
Moving Releases
To move releases, use the drag-and-drop operation.
You can move a release to a sprint, a release to a release, a sprint to release or a sprint to a sprint; they will be converted automatically. However, there are some restrictions:
• You cannot drop a (sub)release to itself.
• You cannot drop any sprint to its direct parent release or sprint.
• You cannot drop a (sub)release to any of its direct or indirect children.
This drag-and-drop interaction does not allow the free-sorting of releases and sprints because the order is defined by their release dates (on the same level).If dates are not set or equal, ordering is by name.
Converting Releases to Sprints and Sprints to Releases
There are two options for converting releases and sprints. You can use the drag-and-drop operation or open a (sub)release’s context menu and click Move up That will move that item one level up in the hierarchy.
Move up is only available for sprints because releases do not have any higher level to push them up into.
