    Before you upgrade to Windows Server 2012 R2, you must uninstall WSUS 3.2 from the server.

upgrade-sccm

Yes

upgrade-sccm-2012

For ensuring your role has been removed successfully you can take a look into “SUPSetup.log”

The next step is to uninstall WSUS role from your server:

wsus

Go and tidy up the WSUS by removing all components:

windows-server-update-services

After that, go to “Programs and Features” and remove the “Windows Server Update Services X SPX Console“.

wsus_2008r2

As soon as you made sure all WSUS components removed completely. Open “Services” and disable all SCCM and SQL services:

services

The in-place process is to run Windows Server 2012 R2 set-up

windows-server-2012r2

I suggest to check the latest update:

go-online

upgrade_server

Once the upgrade is completed. it’s time to run and start up the ConfigMgr and SQL services.

upservices

You can install the WSUS role again:

installing_wsus

db-wsus

For getting full support to Windows 10 feature in your environment you have to install KB3095113 in order to enable to your to WSUS to support.

That’s all.

Thank you.
