Migration plan for CMMN

Camunda 7 Topics Discussion & Questions
1

Hello again,
this time I’d like to know if exists something like a migration plan for CMMN? I’ve seen migration plans for process instances (https://docs.camunda.org/manual/7.6/user-guide/process-engine/process-instance-migration/) but what if I have to change something in my CMMN diagram? For example, I’d like to change ifPart in one of my sentries.

Thanks!

Hi,

There is no comparable feature for CMMN at the moment.

Cheers,

My example is pretty strange. Let’s say a case may takes 10 years. In this time a situation can be changed for any reason (for example, changes in the law / manager decision / company policy). What if I have 1000 cases incompatible with current situation?

Your use case is certainly valid. Camunda simply does not (yet) have a dedicated feature for it. You could think about workarounds involving deploying both CMMMN models and then programmatically “migrate” case instances by replaying case state or similar.

Thanks for explain!
