Aside from migrating the process definitions from jPDL to BPMN and changing the api's, how are existing task instances that are created in jbpm 3 handled after the upgrade?
Which approach should be used?
- Convert the jbpm 3 task instances to jbpm 5? How would this be done?
- Have both jbpm 3 and jbpm 5 installed at the same time so jbpm 3 task instances finish using jbpm 3 and new task instances use jbpm 5.
- Some other solution.
What have other projects done to handle this?
Thanks.
