I'm looking for a some kind of generic guide about the steps to perform during the migration from a BPEL engine to a BPMN engine. Maybe there is some kind of documentation regarding this topic from someone who already did it. Maybe somebody could sketch the necessary steps here. Unfortunately I couldn't find anything appropriate about this topic on the web.
Thanks in advance.
This is not a trivial task.
Do you need to generate "code" (From Bpel to Bpmn) or a transparent migration?
Please take a look on these articles, they show some differences between Bpel and BPMN.
