How to perform an online replacement of an MD controller with your DeltaV Distributed Control System

In this video, we will perform an online replacement of a DeltaV MD Controller to a DeltaV MQ Controller. The same procedure can also be performed to replace your MD+ controller. This online replacement can be performed without affecting your process when you have redundant controllers.

Doesn't work right. DeltaV doesn't recognize the new controller.

Problem was smart switches were locked. Yep, turns out I'm the idiot, not Emerson. Although considering adding the step to check for that in the video.
