I think you are trying to migrate existing process-instances to use a new process-definition that is deployed in the new BAR-file. Can you confirm I'm understanding you correctly?

You can use the org.activiti.engine.impl.cmd.SetProcessDefinitionVersionCmd:


/**
 * {@link Command} that changes the process definition version of an existing
 * process instance.
 * 
 * Warning: This command will NOT perform any migration magic and simply set the
 * process definition version in the database, assuming that the user knows,
 * what he or she is doing.
 * 
 * This is only useful for simple migrations. The new process definition MUST
 * have the exact same activity id to make it still run.
 * 
 * Furthermore, activities referenced by sub-executions and jobs that belong to
 * the process instance MUST exist in the new process definition version.
 * 
 * The command will fail, if there is already a {@link ProcessInstance} or
 * {@link HistoricProcessInstance} using the new process definition version and
 * the same business key as the {@link ProcessInstance} that is to be migrated.
 * 
 * If the process instance is not currently waiting but actively running, then
 * this would be a case for optimistic locking, meaning either the version
 * update or the "real work" wins, i.e., this is a race condition.
