You can delete only active projects—that is, projects whose deployment task is still pending. When you delete an active project, the system deletes from the database the project and all objects associated with it. All working versions of project assets are discarded.
To delete a project, you must be the owner of its current task, or the task must be unassigned.
To delete an active project:
Navigate to the project’s Tasks tab.
From the Select Action drop-down list, choose Delete Project.
Click Go.
A confirmation dialog appears.
Note: The deletion is irreversible, and all working versions of the project assets are also removed from the system.
Click OK.
