We can see how to remove objects from workflows, but there is no way to bring existing objects into their correct workflow in bulk.
This is critical to us adopting workflows, because when a user sees a list of tasks they must complete, we must ensure it is a full list of their OpenPages assignments.
We also have concerns that the approach of maintaining objects in prior versions of workflow / associated task views, may constrain us in future changes. As above, we'd want the admin users to be able to bulk move cases into the new workflow / task view, not be stuck with inconsistent user experience depending on the creation date of the object.
