Planning your Operations Manager 2007 Upgrade
Applies To: Operations Manager 2007 R2, Operations Manager 2007 SP1
Upgrading an installation of Microsoft System Center Operations Manager 2007 is a multistep process. Before you can upgrade your monitoring environment, you need to understand exactly what you are upgrading, the pre-upgrade steps, and the implications for your day-to-day operations.
If your current Operations Manager 2007 installation is at the SP1 (6278) level, you can upgrade directly to the R2 version. The following diagram shows all the supported upgrade paths for Operations Manager 2007.
If you are currently using Microsoft SQL Server 2005 and want to upgrade to SQL Server 2008, you need to take several steps to ensure that Operations Manager 2007 R2 will work with the newer version of SQL Server. For information, see Upgrading SQL Server 2005 to SQL Server 2008.
The following topics outline the pre-upgrade and upgrade tasks and their orders.
