There is a warning in Update 3: "Upon updating the Primary and Satellite Servers to ZENworks 2020 Update 3a, all managed devices with ZENworks 2017 Update 1 or older agents will cease to communicate with servers. It is strongly recommended to update such agents to ZENworks 2020 Update 2 before initiating server upgrade. For information, see ZENworks Best Practices Guide."
But in the video posted today there is an image showing that you can update agents 11.4 to 20.2 straight to 20.3. Would this update for 11.4-17.1 agents be done offline?
