My parents’ house had what sounds exactly like your patio door arrangement. It wasn’t necessary to remove the frame/jamb from the opening to get either the rolling or stationary door out of the frame. The rolling door just lifted out of the track, swinging the bottom out till free. The stationary one removed in the same way, except that there were one or two screws in the frame which had to be removed to allow the door to be lifted. But if you are just replacing the rollers, why do you need to remove the stationary door?
