This section provides information on upgrading your Linux or Windows Primary Servers to ZENworks 2020 . To migrate you Appliance server, see Appliance Migration.
NOTE:If a zone with multiple Primary Server has added support for newly released versions of OS, then consolidate the effective user-defined targets in the custom_ostargets.xml of master primary and update the master Primary Server first.
Using the ZENworks 2020 installation media, you can directly upgrade a Primary Server to ZENworks 2020 if it is using ZENworks 2017.
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 2017 Update x. 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.
NOTE:ZENworks does not support a major version upgrade of an operating system on a Primary Server. For example, you cannot upgrade from SLES 11 SP4 to SLES 12.x. However, you can upgrade the operating system to a minor version. For example, from SLES 12 SP3 to SLES 12 SP4.
IMPORTANT:Do not extract the ISO image and use it to install. The installation must be run from an installation DVD.
