Upgrading the SCCM 2012 R2 lab to SCCM 1511 is simple as long as you prepare your environment and make sure you backup your system. This is the first step, but I’m also planning to upgrade to 1607, so we can get started in deploying Windows 10 with SCCM and migrating MDT within our SCCM server. Big thank you for Anthony E, for hooking us up with the ISO files to continue our series.
To upgrade your SCCM server it takes some prepping and it depends on the actual SCCM version you have to determine if you are able to upgrade successful. Here are the path requirements:
- You can upgrade directly to SCCM 1511 if you’re running the following versions. Cumulative Update are not mandatory)
- SCCM 2012 SP1
- SCCM 2012 SP2
- SCCM 2012 R2
- SCCM 2012 R2 SP1
- If you’re running SCCM 2012 (non-SP), you need to apply first install Service Pack 1 or Service Pack 2 before upgrading.
- If you’re running a Technical Preview on your lab server. Completely uninstall it before doing a fresh install. An upgrade is not supported from a Technical Preview version
- If you’re running SCCM 2007 a side-by-side migration is still possible but you must first start by a fresh install on a separate server. Supported SCCM 2007 is SP2+
- If you have a hierarchy with a Central Administration Site and multiple Primary Site, start with the top of the hierarchy (CAS) and go down, upgrading all Primary Sites and Secondary Sites.
- You need to upgrade your ADK version to version 10 before the upgrade process.
- If you’re planning to use Windows 10 Servicing, you need to consider applying this important WSUS update to your Windows Server.
Step 1: Get your copy of the latest Windows ADK files
Step 19: This is the scary part, because if you have any errors it won’t let you upgrade. I only received three warnings do the the SQL setup. Fix your error and warnings and click on Begin Install to start the upgrade process
