If you have ZENworks 2017 managed devices or Satellite Servers in your network and want to register the devices to a new ZENworks 2020 Update 2 Management Zone so that they can be automatically upgraded to ZENworks 2020 Update 2, you must import the ZENworks 2020 System Update into the zone from the ZENworks 2020 Update 2 installation media.
From ZENworks 2020 onwards, promoting a 32-bit device as a Satellite Server is not supported.
