Planning your Operations Manager 2007 Upgrade

Updated: May 22, 2009

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.

Pre-upgrade Tasks

The following table shows the tasks you need to complete before you upgrade your Operations Manager 2007 installation. This table provides the following information:

  • Task to complete

  • Whether this task results in the service being completely unavailable

  • Whether this task interferes with the service

  • Risk (to the stability of your data and monitoring environment)

  • Mitigation (of downtime, interference, or risk)

Step-by-step information for each of the pre-upgrade tasks is available in the Preparing to Upgrade Operations Manager 2007 topic.
