Before updating a Satellite Server or managed device from a supported ZENworks version to ZENworks 2020 Update 3, you must complete the following tasks:
NOTE:For information about the supported versions, see the ZENworks 2020 Update 3 System Requirements.
Ensure that the device meets the minimum system requirements for ZENworks.
For more information on managed device requirements, see ZENworks 2020 Update 3 System Requirements.
Ensure that the Microsoft .NET 4.8, or later framework and its latest updates are installed and running on the device.
Ensure that the Windows Installer 4.5 or later version is installed.
Ensure that all the Primary Servers in the zone have been upgraded to ZENworks 2020 Update 3.
If you choose to deploy the System Update in stages, ensure that the stage that you create contains at least one stage member (an individual device and a group that contain devices).
Ensure that the Update for ZENworks 2020 Update 3 displays in the Available System Updates list in ZCC. If it is not available, then run the following command to import the update:
zman sui <Path of the system update zip file>
Agents with Windows XP would have to remain on ZENworks 11, as Windows XP is not supported from ZENworks 2017 onwards.
