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
