Upgrading Operations Manager 2007 R2 Agents in a Distributed Management Group

You can upgrade System Center Operations Manager 2007 R2 agents in a distributed management group by using the Operations console, or manually, by using the Setup Wizard or by using a command prompt. Determining which option to use depends on how the agents were deployed. For example, you can upgrade agents that were installed by using the Computer and Device Management Wizard (“push-installed agents”) through the Operations console. However, agents that were installed manually (“manually installed agents”) cannot be upgraded this way. You can use the Upgrade Helper management pack to verify how agents were installed. For more information, see Upgrade Helper Management Pack.

You should upgrade manually installed agents before you run upgrade on the secondary management server. Push-installed agents can be upgraded after you run upgrade on the secondary management server, before you upgrade the management group. You use the Operations Manager 2007 R2 Operations console to upgrade push-installed agents in a distributed topology.

When you move the push-installed agents to a secondary management server by using the Operations console, they are placed in Pending Management, and you must approve the update to upgrade the agents to System Center 2012 – Operations Manager.
