Upgrading a Distributed Operations Manager 2007 R2 Environment
When you upgrade a distributed System Center Operations Manager 2007 R2 environment to System Center 2012 – Operations Manager, you start by upgrading any manually installed agents, followed by the secondary management servers, gateways, and any push-installed agents. You then run upgrade of the management server either on the root management server (RMS), if it meets the minimum supported configurations for Operations Manager, or from the secondary management server if it does not meet these requirements. You can then upgrade additional, optional features, such as consoles, the Reporting server, and the Audit Collection Services (ACS) Collector.
Before you follow any of these procedures, make sure that you verify that the servers in your Operations Manager 2007 R2 management group meet the minimum supported configurations for System Center 2012 – Operations Manager. This will help you determine whether you need to add any new servers to your management group before you upgrade. For more information, see Supported Configurations for System Center 2012 – Operations Manager.
The following topics describe how to perform the necessary steps in a distributed management group upgrade. The specific upgrade path you take depends on your current environment. For information on choosing an upgrade path, see Upgrade Path Checklists for Operations Manager.
