A new version of the System Center Operations Manager 2007 Backup and Restore Guide has been released to web. In this updated version, we provide procedures for moving the OperationsManagerDW (Data Warehouse) and the OperationsManagerACS (Audit Collection) databases.
It can be downloaded from the Operations Manager 2007 Product Documentation page off of TechCenter - http://technet.microsoft.com/en-us/opsmgr/bb498235.aspx
We realize there are other scenarios still outstanding, such as moving the Operations Manager Reporting component. Please bear with us as we work hard to complete that and other scenarios for the Backup and Restore Guide.
