10.1.2. to 10.1.3 Human workflow task migration issue

Question

Hi all,
I am currently looking at the possibility to migrate our 10.1.2 bpel processes, containing human workflow task, to 10.1.3.1.0 Everything seems to migrate smoothly except the human workflow functionality.
The initateTask invoke action returns the following error in the 10.1.3.1 console when I ran an 10.1.2. bpel process containing a human workflow task:
[2006/12/04 03:01:00]

Make sure wsdl is valid. You may need to start the OraBPEL server, or make sure the related bpel process is deployed correctly.

I know that in 10.1.3 the human workflow mechanism is heavily changed and now is invoked by using other services (TaskService) than the services used (TaskActionHandler process)in 10.1.2. In 10.1.2 the TaskActionHandler was a separate build-in bpel process used for interaction between a bpel process and the human workflow. This process is not present in the 10.1.3.1 installation, so that is causing my error. Moreover, in 10.1.3 the interaction between a bpel process is and the human workflow is not done by invoking a separate bpel process (TaskActionHandler) but by invoking a java wsif service TaskService..(Correct me when I'm wrong or not complete)
My question now is how can I migrate my 10.1.2 human workflow task to 10.1.3.1 without manually rewrite the task scopes to 10.1.3...According to the fragment below copied from the JDeveloper 10.1.3.1 help files it should be possible. Maybe, there's is a way to deploy the needed processes manually?
Oracle BPEL Process Manager Workflow Services 10.1.2 and 10.1.3.1.0 Compatibility
For release 10.1.3.1.0, the workflow wizard has been replaced by a Human Task editor. This editor enables you to specify task settings such as task outcome, payload structure, task participants, assignment and routing policy, expiration and escalation policy, notification settings, and so on. You cannot use the Human Task editor to edit 10.1.2-based workflows. To use any new 10.1.3.1.0 functionality, the task scope of the workflow must be manually migrated to use the new workflow metadata. Note also that this is the last release in which you can deploy workflows designed with 10.1.2.

Hi Clemens,
Thanks for your quick response. The Taskmanager and the Taskactionhandler are indeed not deployed so I will do that automatically.
Still one question/remark left:
You noticed that you still have to complete the tasks using the old worklist app. . So if i'm correct, you have to use the deprecated 10.1.2 worklist api or build-in worklist app. The 10.1.2 worklist app is not deployed in my 10.1.3 installation. However, 10.1.3 only contains the new worklist app. Is there also a way to deploy it manually?
Writing this down it al looks a bit clumsy to me. Is it not a better option to invest some time in migrating all tasks scopes manually to 10.1.3, because as far as I can see the human tasks are causing the main issues concerning migration? After this you have a 10.1.3 compliant system. I wonder what your opinion is on this issue.
Kind regards,
Tom
