As another part of my series for Windows Server 2019, this blog post covers the in-place upgrade feature. In-place upgrade allows you to upgrade your existing LTSC versions of Windows Server 2012 R2 or Windows Server 2016 servers to Windows Server 2019. Windows Server 2019 In-place Upgrade allows businesses to quicker update to the latest version. Especially, if you have servers which you might needed to install some dependencies for the applications. I saw a lot of customers which not have documented their server installations and neither used infrastructure as code to deploy them. For these customers it can be hard to upgrade to newer versions of Windows Server. With the Windows Server 2019 In-Place Upgrade feature, this should get a lot easier. Especially since Windows Server 2019 bring a lot of improvements.
You can in place upgrade to Windows Server 2019 from
- Windows Server 2012 R2
- Windows Server 2016

The installation will run for a couple of minutes, it will take quiet some time depending of the speed of your server hardware and of the installed roles and features.
