Issue

How does jBPM engine support process model and rule versioning and version update. Can we run multiple version at the same time? For example, at the production environment, I may have a process running and is not completed yet, but we need to update the process model with fix or enhancement--> a new deployment is needed. Under this case, we update the jar file or Guvnor JCR repository with the process model, how does it work?

1. Is the previous version of process model removed?
2. The pre-existing running process should still be working fine with the old version?
3. Does jBPM support running multiple versions at the same time? How does it work for asset in the jar file and asset in Guvnor JCR repository
4. If #3 is not supported, what is the best practice for process model upgrade/update to migrate the previous running version to new version?
5. What is the versioning support for jBPM 5 REST API and in business-central ?
6. How is the guvnor version attribute and bpm2 version attribute connected ?
