Upgrading to Configuration Manager 2012 R2

In this post I am describing the simple upgrade scenario from Configuration Manager 2012 SP1 to Configuration Manager 2012 R2. The scenario starts with a standalone primary site with Configuration Manager 2012 SP1 installed on Windows Server 2012 RTM and SQL Server 2012 CU2. In this case both the operating system and the database are supported by Configuration Manager 2012 R2, so no need to change them.

By running the Prerequisite Checker from the Configuration Manager 2012 R2 installation media (\SMSSETUP\BIN\X64\prereqchk.exe) we can see that we need to remove Windows ADK 8.0 (which was the supported version for Configuration Manager 2012 SP1) and need to install Windows ADK 8.1 which includes support for Windows 8.1 and Windows Server 2012 R2.

Windows ADK 8.1 is not included on the installation media, so we need to download it. It is recommended to download the entire installation package (2.85 GB) rather than installing it directly from the Internet. On a computer with Internet connection, navigate to http://go.microsoft.com/fwlink/?LinkId=301570 and run the setup, then select the option to download Windows ADK 8.1 to a local folder.

Remove Windows ADK 8.0 by using Program and Features applet in Control Panel, then run the installer for Windows ADK 8.1. Select the options to install:

  • Deployment Tools
  • Windows Preinstallation Environment (Windows PE)
  • User State Migration Tool (USMT)

If the computer where you are installing Configuration Manager 2012 R2 does not have direct Internet connectivity, it is recommended to run the Setup Downloader (\SMSSETUP\BIN\X64\setupdl.exe) on another computer with Internet connection, and download the latest version  of the Configuration Manager prerequisites to a local folder.

Run the setup for installing Configuration Manager 2012 R2 from the installation media. The setup will detect automatically that a previous version is installed and will offer the option to Upgrade this Configuration Manager site.

Finish the setup wizard. After upgrade the site will show the version 5.0.7958.1000.

After upgrading the primary site server, you will need to upgrade/reinstall other site systems as needed and upgrade the Configuration Manager clients.
