Hello, When you deploy a processdefinition (xml,par file) with a name that already exists in DB, a new procedefinition is created (and the nodes etc ...) in the DB with a new version number. If I load a processdefinition with the API, change the node and deploy with the method on GraphSession Class, a new definition is inserted with a new version number but the nodes are updated and not created. The definition with the verison number - 1 doesn't have anymore nodes. How can I have the same behavior trough the API : deploy a new version of a process definition that I have previously loaded ?
