Dynamic assignment of users to BPM roles

Hello supprt,
when a process definition changes, I think the already existing process intances keep the old definition. Is this right? Do you have a proposal about how to implement a functionality that gives all existing instances the new process definition?

Kind regards

Sorry, we missed this question somehow. I understand that you probably don’t already need the help, but for others who will come into this topic, the answer may be helpful.
So, when the process is deployed, all process instances automatically migrates to the new process definition.
