yeah. I meant after adding the new tasks which you need for sure the tasks are named, esp, "mirror0" and "mirror1" and the server which hasn't been replaced and "mirror0_reverse" and "mirror1_reverse" on the new one which has been replaced.
Typically, in a active/active scenario, you create one task with one volume as source on one server, and one task on the other server with the other volume as source.
So on one server its tasks mirror0 and mirror1_reverse and on the other server its mirror0_reverse and mirror1
