----------------------------------

Bernd, could you commit that ?   I want to have a look and see if we can base an experimental implementation on that.

> i think jbpm could offer some degree of assistence in process instance versioning.  
> when a new version of a process is deployed, jbpm could do the following conversion for a process instance : 
> * input required: mapping of the nodes from the old to the new definition.
> * cancel the old process instance
> * create a new process instance and copy the runtime (exe) information such as tokens and process variables from the old process instance.  
> * then establish a special link between the 2 process instances to indicate that the new process instance is the continuation of the old process instance.
> this way we can avoid the problematic conversion of logs, while still keeping them in the system.
