Update the Published Process

If you make any changes to the published process, you must publish the diagram again for those changes to appear.

Open the BPMN diagram from the Diagrams tab and make your changes. Once you are done with the changes, you can update the diagram as given in the Publish a BPMN Diagram article.

While publishing, the current published process (old diagram) and the updated process (new diagram) appear. You can compare and verify the changes before publishing.
