Look at workflow_history attribute on document, it's easy to understand 
how it's structured (with pprint).
This http://svn.erp5.org/?view=rev&revision=17171 was to change the 
state variable name, so it's not exactly the same. If only workflow ID 
changed, I think you can simply do:
ob.workflow_history['new_workflow_id'] =\
          ob.workflow_history.pop('old_workflow_id')
