I've had a workflow that has been deployed into our production environment for over a year. While it works well, the users have requested a major change that will require the addition of a new SmartObject and multiple views.
This is the first time that an existing workflow is going to need a larger renovation beyond adding a single field. I am most concerned about what happens on Production to Historical instances that won't have the same structure.
If I deploy a new workflow over to Production, and the Form now opens additional views, what happens to the previously completed items? (We have a list that users can open up Historical Views of "what happened"). Will these historical views use the new forms?
I tried to look for more details on this and I couldn't seem to find guidance/best practices on this area.
