Hi, I am looking for documentation to upgrade from drools jbpm 5.1 to 5.2. It seems that the variable persistence strategies have been replaced with a object marshaling strategy architecture. I can't find documentation regarding this. I am using jpa persistence for my flow state. Is there some sort of migration script to migrate the jbpm domain model from 5.1 to 5.2.
