Using the ZENworks 2020 Update 2 installation media, you can directly upgrade or migrate a Primary Server to ZENworks 2020 Update 2, if it is using ZENworks 2020 or later.
If the upgrade installer reports any of the following issues during the upgrade, follow the recommended procedures to resolve the problem:
Unsupported ZENworks version: Upgrade all Primary Servers to ZENworks 2020 Update 2. Ensure that all Primary Servers in the zone have the same version of ZENworks.
Unsupported operating systems: Upgrade the operating systems to a supported version.
For more information about the discontinued operating systems, see the System Requirements.
On Linux (including appliances), during the upgrade, the "zenworks" user and "zenworks" group IDs maybe be changed to 525 (/etc/passwd and /etc/group files respectively). If there is any mechanism in the environment to prevent this or unable to rewrite the changes, then ZENworks might break.
If the zone with multiple Primary Servers has added support for newly released versions of OS, then consolidate the effective user-defined targets in the custom_ostargets.xml of the master primary and update the master primary server first.
IMPORTANT:Do not extract the ISO image and use it to install. The installation must be run from an installation DVD.
