All the Primary Servers should be updated before you update the agents and the Satellite Servers in the zone. To ensure the proper functioning of ZENworks, it is recommended that all Primary Servers are updated in as short a time as possible - ideally, immediately after the first Primary Server is updated.
The administrator can always choose to update one of the Primary Servers and then the remaining Primary Servers. The Primary Server that is chosen to be updated first should be the server with the embedded database.
NOTE:
The ZENworks Updater Service should be running to initiate an update on Primary Servers and Windows Agents.
The ZENworks Agent Service should be running to initiate an update on Linux Agents.
If the zone contains an embedded database, the server that is running in the database should be updated first.
Before updating the ZENworks Agent on managed devices, ensure that any reboots required from applying a policy are completed.
If the zone contains one or more SLES 12 or SLES 15 non-appliance primary servers, for the ZENworks 23.4 system update, ensure that the ‘libseccomp2’ package is at 2.4.1-11.3.2 or later version.
Vertica Prerequisite When updating a Vertica enabled zone to ZENworks 23.4, a new pre-requisite check is introduced to verify the Vertica version in the zone. If the version is lower than Vertica 23.3, then you need to upgrade to the latest version by using the Vertica Upgrade tool. For more information on the tool and how to run the tool, see Upgrading Vertica in the ZENworks Vertica Guide.
