After the upgrade is complete, perform a quick health check on your ePO - On-prem server.
Note
ePO - On-prem 5.10 can no longer connect to a registered server that requires TLS certificates but does not support TLS 1.1 or 1.2. For more information, see Update your database server certificates.
Confirm you can log on and access different areas of the ePO - On-prem console.
Update your certificates to SHA-2 if a warning appears on the ePO - On-prem logon screen. For details, see Migrate Certificate Authority Hashtag Algorithm from SHA-1 to SHA-2 or higher.
Verify connectivity by sending an agent wake-up call to one or more systems.
Verify ePO - On-prem is operating correctly by running a query or server task.
Make sure that your policies, tasks, product deployments, and repositories reflect the choices you made when you set up your environment.
Test the connection to all your registered servers. If any server fails that uses SSL, it might need to be updated to support TLS 1.1 or higher for ePO - On-prem to successfully connect to it.
Apply the available update to ePO - On-prem and all Agent Handlers. For details, see Trellix ePO Cumulative Updates.
Enable any server tasks you disabled before upgrading. For more details on supported upgrade paths, see KB96141.
Enable Windows updates to make sure that your servers receive the latest updates for your operating system.
Apply the latest update when the upgrade is complete.
