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.
All the primary servers can be updated simultaneously by assigning the system update to all servers in the zone. However, the administrator can always choose to update one of the Primary Servers and then the remaining Primary Servers.
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 a dedicated system update server is configured in the zone, this server should be the first to be updated.
Before updating the ZENworks Agent on managed devices, ensure that any reboots required from applying a policy are completed.
If you are updating multiple agents, you can use a Quick Task in the ZENworks Control Center to reboot multiple devices after disabling Client Self Defense. For information about the Quick Task feature, see Using Quick Tasks
in the ZENworks Control Center Reference.
