A: Configuration Manager supports an in-place upgrade from System Center 2012 Configuration Manager 2012 to SP1. Launch the setup process from the SP1 media. The option to upgrade the existing site will be offered and selected by default. Prior to starting the upgrade, however, you should ensure the following requirements have been met:
- Confirm your SQL Server database meets requirements, as documented at the Microsoft article "Supported Configurations for Configuration Manager, Configurations for the SQL Server Site Database." If you are running SQL Server 2008 R2, you need to install CU6 for SP1 or install SP2 (see the Microsoft download site for details).
- Two updates for WSUS 3.0 SP2 must be applied, which can be downloaded from the Microsoft Support pages "An update for Windows Server Update Services 3.0 Service Pack 2 is available" and "An update for Windows Server Update Services 3.0 Service Pack 2 is available (KB2734608)."
- You must install the User State Migration Tool (USMT), Windows Deployment Tools, and Windows Preinstallation Environment from the Windows 8 Assessment and Deployment Kit (ADK) which can be downloaded from the Microsoft download site.
During the upgrade all prerequisites will be checked, and assuming everything is in place, the upgrade of the site will complete without further user intervention.
