I guess there was more to the question. I was thinking about my answer, and the only part of it that I am not sure about is after adding a user to a role, then does that user get included in the next task along. That aside, it is not practical to have DocuWare traverse every workflow instance in progress and check for changes from any aspect of DocuWare Administration. Certainly once a task is allocated to users, it cannot be changed. The tasks will have to be manually re-assigned. Even subsitution lists will not move a users current task away from them once allocated unless it becomes subject to some overdue rule or what have you.
Of course, if it was me faced with moving a lot of tasks from one user to another, depending on the circumstances, I would either make the other user a Controller temporarily, or have them log in as the first user. But I'd only do that if re-assignment was completely onerous for some reason.
