SharePoint 2010 and Windows 2012 R2 support


I needed to install SharePoint 2010 on Windows Server 2012 R2, but I needed to check if SharePoint 2010 had support for Windows server 2012 R2. Luckily Microsoft had updated the KB article for SharePoint 2010 Service Pack 2. It is now possible to install SharePoint 2010 on Windows Server 2012 R2. The following was added to the article:

Note: Deployments from the slipstream media at Microsoft Volume License Service Center (VLSC) and MSDN can now be performed on Windows Server 2012 R2 as of May 1, 2014.

But that’s not all, apparently you need to install at a minimum the February 2014 CU or later in order to have support! So you have to slipstream or install the February 2014 CU or later after installation.

Some other things to consider when upgrading to Windows Server 2012 R2:

SharePoint does NOT support installing Service Pack 2, the February 2014 CU or later and then upgrading the OS to Windows Server 2012 R2. So OS in place upgrade is NOT supported! The correct steps for upgrading the OS (for the SharePoint server) in your farm is simple.

1. Patch your farm with Service Pack 2.

2. Patch your farm with the February 2014 CU or later.

3. Build a new Windows Server 2012 R2 server, install SharePoint with Service Pack 2 and the February 2014 CU or later and add it to the farm.

4. When you have added a new server and configured it, take an older server out of the farm until they are gone.

Make sure you plan and test this! Don’t forget to backup the old servers and check if all changes, tweaks and certificates have been transferred to the new servers.
