When an interactive flowchart is no longer needed, you can mark it for undeployment. This adds the retirement request to the deployment queue. The next time that all changes are deployed, the interactive flowchart is removed from the Interact server. Treatment rules that contain the smart segments that are created by the flowchart you removed still exist, however, since there is no interactive flowchart to assign a visitor to that segment, no visitor is assigned to the segments created by the flowchart that you removed.
