Users with the queue_admin or queue_manager role can move a task from one work queue to another work queue.
To move a task from one queue to another queue:
If the task you want to move is already assigned to a user, you must first unassign the task, as described in Unassigning a work queue task from a user.
In the Classic view’s left pane, click Work Queue Monitoring.
Navigate to the active work queue, and click it’s name.
Select the checkbox for one or more tasks.
Select Tools>Work Queue Management>Move to Queue.
Select the work queue to which you want to reassign the tasks.
Click OK.
