How To Upgrade to SCCM 1606 from SCCM 2012 R2

In this article we’ll go over the Upgrade to SCCM 1606 from System Center version 2012 R2. In my environment, we were late bloomers when it came to upgrading our System Center environment, mostly because as a sysadmin, we we’re tasked with multiple projects and upgrading our SCCM environment wasn’t that high on the priority list. I’m sure many of you sysadmins who wear multiple hats can relate. However, I am more than happy that I finally was able to upgrade it. The new features in 1606 are awesome and I only wish I had done it sooner.

My lab environment is somewhat a replica to my production environment. Meaning that I have a dedicated domain controller (two actually), a dedicated SQL server running 2012 Standard and a dedicated SCCM server all running Windows Server 2012 R2. I should mention that it’s not necessary to run all of these servers individually and I know many people that are just starting out do not have the resources, I just wanted to provide a layout of my environment so you have an understanding of what I am using. If resources are an issue, you can run all of these on a single server and it should get the job done.

SCCM Upgrade to 1606 Path:

If you’re looking to upgrade to 1606, you can do this in several ways. One way is using the baseline media to upgrade to 1511, then upgrading to 1606. The other method is using the baseline media to upgrade to 1606 directly. In this article, we’re going to use the baseline media to upgrade to 1606 directly.

ADK Version Prerequisite:

SCCM 1606 requires a minimum ADK version of Windows 10 1607. You should be able to check your Programs and Features to see which version you are running. If you’re running ADK version 8.1, you will need to uninstall this version and install the 1607 version.

Our goal is to upgrade our Configuration Manager site so our obvious choice to choose the option to do so.

In my lab I do not have a product key so I will opt for the 180 day eval version. If you’re running this in production, you would want to enter in your license key. Either way, you can click next.

Accept all the license terms and EULA’s to proceed.

The next screen will run the prerequisite checks to ensure that everything will work prior to actually running the upgrade. As long as you don’t get any critical errors it should go pretty smooth. I believe it won’t even let you continue until all critical prerequisites are fixed. Click Begin Install and we’re off to the races.
