Changing the Lifecycle of an Active Project

An active project may have approved Stages in its Lifecycle. It is not possible to delete or edit approved Stages.

However, you can replace your existing Lifecycle with a new Lifecycle that takes into account that an approved stage needs to be extended, the stage was approved by mistake, or a decision has made to follow a different methodology.
