!!!! WARNING: !!!! The Delete Process Model Version smart service should be executed over versions you don't have running instances on. You can use a process model report to determine whether you can safely delete versions or not. The reason being this will delete the XMLs from the file system as well , which are used by running instances. Make sure you delete only those versions from which you no longer have process instances running.
