Thanks for the answers. But what I do is more complicated. I use DefaultMigrationHandler from external code. My definitions have the different names and the second has not migration tag. Here is my testcase that represent my use case (simplified):

    public void testMigrateRunning()
      {
        deployJpdlClasspath("org/uni/stuttgart/iaas/fragments/test/a.jpdl.xml");


        ProcessInstance processInstance = executionService
            .startProcessInstanceById("a-1");
        assertTrue(processInstance.isActive("a"));


        String id = processInstance.getId();
        processInstance = executionService.signalExecutionById(id);
        assertTrue(processInstance.isActive("x"));




        deployJpdlClasspath("org/uni/stuttgart/iaas/fragments/test/b.jpdl.xml");




        processInstance = executionService.signalExecutionById(id);
        assertTrue(processInstance.isActive("b"));
        processInstance = executionService.signalExecutionById(id);
        assertTrue(processInstance.isEnded());
      }


    public void testMigrateRunningIntern()
      {
        deployJpdlClasspath("org/uni/stuttgart/iaas/fragments/test/a.jpdl.xml");


        ProcessInstance processInstance = executionService
            .startProcessInstanceById("a-1");
        assertTrue(processInstance.isActive("a"));


        String id = processInstance.getId();
        processInstance = executionService.signalExecutionById(id);
        assertTrue(processInstance.isActive("x"));




        String deploymentId = deployJpdlClasspath("org/uni/stuttgart/iaas/fragments/test/c.jpdl.xml");
        // Get new process definition
        ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery().deploymentId(
            deploymentId).uniqueResult();
        assertTrue(processDefinition.getName().equalsIgnoreCase("c"));
        // Migrate instance here
        new DefaultMigrationHandler().migrateInstance(processDefinition, processInstance, new MigrationDescriptor());




        processInstance = executionService.signalExecutionById(id);
        assertTrue(processInstance.isActive("b"));
        processInstance = executionService.signalExecutionById(id);
        assertTrue(processInstance.isEnded());
      }

The first test is ok, the second is failed.

Any help would be appreciated.
