    Migrating process instances from jBPM 4.4 to jBPM 5.3

    patricia_b

      The application that I am working is using jBPM 4.4 and I am investigating how to migrate to jBPM 5.3. The main concern that I have is that we currently have some existing process instances that would need to be migrated as part of the upgrade. I have searched the documentation, and the migration tool seems to be only for process definitions - migrate the jPDL to BPMN2.0.

       

      What would be the recommended approach here?

       

      Thanks

          I am afraid that is more of manual procedure, there is migration project but it intended to migrate from jBPM 3.x into 5 but it focuses only on process definition and not running processes. What you will need to do is probably introduce some kind of transitions stage that will run both engines at the same time where new instances will be started on jBPM5 and those that are already running will continue on 4.4 until they reach the end.
