Upgrade from 6.3 to latest version

1.Stop the ERA Server cluster Role in the Cluster Manager. Make sure the ESET Remote Administrator Server service is stopped on all cluster nodes.

2.Get the cluster shared disk online on node1 and upgrade ERA Server manually by executing the latest .msi installer as in case of a component installation. After the installation (upgrade) is finished, make sure the ESET Remote Administrator Server service is stopped.

3.Get the cluster shared disk online on node2 and upgrade ERA Server  the same way as in step no. 2.

4.Once ERA Server is updated on all cluster nodes, start the ERA Server Role in the Cluster Manager.

5.Upgrade ERA Agent manually by executing the latest .msi installer on all cluster nodes.

6.In ERA Console check if Agent and Server versions for all nodes report the latest version to which you upgraded to.

Manual for upgrade from version 6.1 or 6.2 to version 6.3

Please note that for older ERA versions the ERA Agent service was running always only on the active node in the failover cluster. Starting with ERA 6.3, the ERA Agent service is running on all nodes all the time. This way all nodes can be monitored by ERA all the time.
Please be aware, that the change described above will cause that during upgrade new computer will be created at least for one of the cluster nodes. If you do not need event history for them, do not forget to manually remove the old computer(s) via ERA Console.

 

1.Stop the ERA Server cluster Role in the Cluster Manager. Make sure the ESET Remote Administrator Server and service is stopped on all cluster nodes.

2.If the ERA Agent service was set as a dependency or resource for the ERA Server Role, remove the ERA Agent resource/service completely from the Cluster manager.

3.Get the cluster shared disk online on node1 and upgrade ERA Server manually by executing the latest .msi installer as in case of a component installation. After the installation (upgrade) is finished, make sure the ESET Remote Administrator Server service is stopped.

4.Get the cluster shared disk online on node2 and upgrade ERA Server  the same way as in step no. 3.

5.Get the cluster shared disk online on node1 and uninstall the old version of ERA Agent (6.1 or 6.2).

6.Get the cluster shared disk online on node2 and uninstall the old version of ERA Agent (6.1 or 6.2).

7.Start the ERA Server cluster Role in the Cluster Manager.

8.Install ERA Agent on all cluster nodes using the standalone installer. In the Agent configuration and Connection to Remote Administrator screens use the hostname of ERA Server cluster Role.

9.In ERA Console check if Agent and Server versions for all nodes report the latest version you upgraded to.
