Hello! Is there any way to modify the structure of an ongoing process instance in runtime (add / delete some elements, gateways, sequence flows etc.) without altering the process definition and restarting? ---

In addition to Martin’s blog post, we are also thinking about adding more features in the Engine to allow you to change the process definition for a specific process instance. But that’s still needs quite a bit of thought on how to best implement this in the Engine. Best regards, Tijs
