After you upgrade the QDB, management server, and Control Center components, you can use Control Center to upgrade agents on remote computers.
In Control Center, you will specify a user account to run the agent installation package. Ensure that the account has the required Group Policy object (GPO) setting. The account must be a member of the Replace a process level token policy, which determines the user accounts that can call the CreateProcessAsUser() application programming interface (API) so that one service can start another. By default, only local system accounts are members of the policy. You can edit the policy in the default domain controller GPO and in the local security policy of workstations and servers. The policy is located in the following path in the Microsoft Management Console:
Computer Configuration\Windows Settings\Security Settings\Local Policies\User Rights Assignment
For more information about upgrading agents on remote Windows computers, see Deploying AppManager to Agent Computers in the Control Center User Guide for AppManager. For information about upgrading agents remotely on UNIX or Linux computers, see the AppManager for UNIX and Linux Servers Management Guide, available on the AppManager Modules Documentation page.
If you previously used Performance Monitor to monitor the operational health and performance of agents, you must manually update the performance counters after the upgrade. For more information about manually updating the counters, see Section 3.5.2, Updating Agent Performance Counters.
