Checklist for Upgrading to System Center 2012–Operations Manager (Single-server Upgrade)

The upgrade to System Center 2012 – Operations Manager is supported only from Operations Manager 2007 R2 CU4, or from the latest available CU. Before beginning the upgrade process, make sure that all the servers in the management group meet the minimum supported configurations for System Center 2012 – Operations Manager.  For more information, see Supported Configurations for System Center 2012 – Operations Manager.

There are four upgrade paths. The path you choose depends on your current topology and system configurations. The following table describes the upgrade paths in more detail.

Single-server Upgrade (Simple)

Use this upgrade path when you have an Operations Manager 2007 R2 management group where all features are installed on the same server, and the hardware and software meets the minimum supported configuration for System Center 2012 – Operations Manager

Single-server Upgrade (Complex)

Use this upgrade path when you have an Operations Manager 2007 R2 management group where all features are installed on the same server, and the hardware and software do not meet the minimum supported configuration for System Center 2012 – Operations Manager. If the operating system on the server is 32-bit, a new, 64-bit server is required.

Distributed Upgrade (Simple)

Use this path when you have an Operations Manager 2007 R2 management group where various features are installed on separate servers, all of which meet the minimum supported configurations for System Center 2012 – Operations Manager.

Distributed Upgrade (Complex)

Use this path when you have an Operations Manager 2007 R2 management group where various features are installed on separate servers, and where one or more servers do not meet the minimum supported configuration for System Center 2012 – Operations Manager. For example, if the RMS is clustered, you must follow this path. If the operating system on any of the server is 32-bit, new 64-bit replacement servers are required.

Pre-Upgrade Tasks for Operations Manager

There are number of pre-upgrade tasks to be performed before you upgrade from System Center Operations Manager 2007 R2 to System Center 2012 – Operations Manager. The order in which you perform these tasks will vary depending on your upgrade path.

In a single-server management group upgrade, you must perform all the applicable pre-upgrade tasks before you start the upgrade process. Service will be interrupted until the upgrade process is completed. If your single-server management group does not meet the minimum system requirements, or you do not want to experience downtime, you can add a secondary management server, and then follow the distributed management group upgrade process.

The following table shows the tasks that you must complete before you upgrade from Operations Manager 2007 R2 to System Center 2012 – Operations Manager.

Verify   the SQL Server Collation The   management group upgrade does not succeed if unsupported collation   configurations exist.
Back   up the Operations Manager Databases Depending   on the backup technology that you use, some backup methods might lock a   database during backup.
Restore   the RMS Encryption Key on the Secondary Management Server No   downtime or interference; low risk.Required   only if the root management server (RMS) does not meet the supported   configuration requirements for System Center 2012 – Operations Manager. This   should be performed just prior to management group upgrade.
Upgrade   SQL Server Reporting Services The   reports will be unavailable, but data will not be lost.

The attached checklist walks you through an upgrade of a System Center Operations Manager 2007 R2 single-server management group that already meets the minimum supported configurations for Operations Manager.
