Verify that all ePO - On-prem servers and agents use the same agent-server secure communication (ASSC) key pair.
Tip
If you have many managed systems in your environment, Trellix recommends performing this process in phases so you can monitor agent updates.
Create an agent update task.
Export the keys chosen from the selected ePO - On-prem server.
Import the exported keys to all other servers.
Designate the imported key as the main on all servers.
Perform two agent wake-up calls.
When all agents are using the new keys, delete any unused keys.
Back up all keys.
