%X How to transfer a workflow instance from the old workflow specification to the new workflow specification is the most challenging issue in evolution of a workflow model. An workflow process model was proposed with relative workflow instance model and change model. A new transferring policy was also presented. Each transfer statement of task node in old specification confirm appropriate action according to the relations between specification change points and excute path of workflow instance, In addition, an algorithm of automatically building transfer rule of each task node according to the partial ordering of change node was put forward.
