Upgrading your ePO - On-prem software in a cluster environment requires special consideration.
Make sure your current environment is supported for the upgrade to ePO - On-prem 5.10.0 Service Pack 1.
In Failover Cluster Manger on the active node, open the ePO group.
Make sure that the primary node is the active server.
Take this Generic Service resource offline:
ePolicy Orchestrator - On-premises Application Server
ePolicy Orchestrator - On-premises Event Parser service
ePolicy Orchestrator - On-premises Server service
Do not change these resources, which are required for a successful upgrade:
Data drive
ePO - On-prem virtual IP address
ePO - On-prem virtual Network Name
Open the Services Control Manager and start each of these services on the primary node:
ePolicy Orchestrator - On-premises Application Server
ePolicy Orchestrator - On-premises Event Parser service
ePolicy Orchestrator - On-premises Server service
Install the new ePO - On-prem software on the primary node.
In Failover Cluster Manager, move the ePO application role to the second node of the cluster: right-click the role, select Move → Select Node. Select the second node of the cluster and click OK.
The role moves to the second node of the cluster.
(Optional) Shut down the first cluster node server, which automatically moves the role to the second node.
Install your new ePO - On-prem software on the second node.
Create the new Generic Service resources.
