Apply Activiti for old project

[greencomet90]

We have flow
start -> service task1 (object A state 1)-> user task 1 ->service task 2 (Object A change to state 2)-> user task2 -> ….
Currently, our project is not apply workflow. If now apply Activiti, the flow for Object A should start at service task 2, How can we achieve it ?

Thanks

With an exclusive gateway after process start that checks for the condition you want and then goes directly to service task 2?

Thanks for response, I think of that before. But my boss said that the flow (go direct to service task 2) is not in business, and we should get the sql code, of the Object A run from start to service task 2, then apply that sql to old variable (at state 2), to create history of old the object at state 2 in database like the history of Object A. Is the using of exclusive gateway the only way?

It's not the only way. It's code, so you can do whatever you want.
The sql route is possible, but it's kinda hacking. And hard to get 100% correct for all cases I believe.
