Reassign Tasks, Responsibilities and Groups for User

Currently there is not any Out of the Box functionality that reassigns a users assignments in bulk to another user.   Entities such as tasks, resource role responsibility assignments, and user group assignments would need to be manually reassigned on each item and the newly assigned users on tasks do not get notification of the reassignment.  This workflow can be used to reassign all tasks, responsibilities, and group assignments from one user to another user and send out a notification regarding the workflow task reassignment.
