Last week I talked about the release of OpsMgr 2007 SP1 so I wanted to take a minute and post a link to the upgrade guide. Depending on where you're coming from there may some gotchas you'll want to keep in mind, so before you head out on the upgrade path be sure to give this a good read:
Upgrading from Microsoft Operations Manager 2007 to Microsoft Operations Manager 2007 Service Pack 1 is a multi-step process. The procedures listed in this section are presented in the order in which they must be completed. Most procedures must be completed on the computer hosting the component being upgraded.
Before upgrading, please read Known Issues with the Operations Manager 2007 SP1 Upgrade at the end of this document where you will find topics such as considerations for agents that are multi-homed between upgraded and non-upgraded management groups.
Note: If you attempt to run SP1Upgrade.exe on a computer that is not hosting an Operations Manager 2007 component, the setup application will close and no warning will be displayed.
To upgrade Operations Manager 2007 to SP1, run SP1Upgrade.exe from either the CD or from the downloaded update.
The following diagram provides an outline of the supported and unsupported upgrade paths.
