Dear all,

I already generate a lot of process instance . For example 100 runtime process instance (not completed)  from process definition  id -> tes:1:1
.
There is situation when i have to modified the process definition.
i upload the modified process definition to server.
the proses definition id  generate  -> tes:2:56

Is it posible   100 runtime process  instance from old process definiton  executed using the modified process definiton ?

Take a look at the org.activiti.engine.impl.cmd.SetProcessDefinitionVersionCmd, this does what you need. Take into consideration the dangers that come with it:

<br>/**<br> * {@link Command} that changes the process definition version of an existing<br> * process instance.<br> * <br> * Warning: This command will NOT perform any migration magic and simply set the<br> * process definition version in the database, assuming that the user knows,<br> * what he or she is doing.<br> * <br> * This is only useful for simple migrations. The new process definition MUST<br> * have the exact same activity id to make it still run.<br> * <br> * Furthermore, activities referenced by sub-executions and jobs that belong to<br> * the process instance MUST exist in the new process definition version.<br> * <br> * The command will fail, if there is already a {@link ProcessInstance} or<br> * {@link HistoricProcessInstance} using the new process definition version and<br> * the same business key as the {@link ProcessInstance} that is to be migrated.<br> * <br> * If the process instance is not currently waiting but actively running, then<br> * this would be a case for optimistic locking, meaning either the version<br> * update or the "real work" wins, i.e., this is a race condition.<br> * <br> * @see <a href="http://forums.activiti.org/en/viewtopic.php?t=2918" rel="nofollow noopener noreferrer">http://forums.activiti.org/en/viewtopic.php?t=2918</a><br> * @author Falko Menge<br> */<br>
