If you want to move to a newer version of Windows Server on the same hardware, one way that always works is a clean installation , where you just install the newer operating system directly over the old one on the same hardware, thus deleting the previous operating system. That is the simplest way, but you will need to back up your data first and plan to reinstall your applications. There are a few things to be aware of, such as system requirements, so be sure to check the details for Windows Server , Windows Server R2 , and Windows Server Moving from any pre-release version such as Windows Server Technical Preview to the released version Windows Server always requires a clean installation.
Windows Server migration documentation helps you migrate one role or feature at a time from a source computer that is running Windows Server to another destination computer that is running Windows Server, either the same or a newer version. For these purposes, migration is defined as moving one role or feature and its data to a different computer, not upgrading the feature on the same computer.
This is the recommended manner in which to move your existing workload and data to a more recent version of Windows Server.

This is called license conversion. For example, if your server is running Windows Server Standard, you can convert it to Windows Server Datacenter. In some releases of Windows Server, you can also freely convert among OEM, volume-licensed, and retail versions with the same command and the appropriate key.

In the classic upgrade, you go from an older operating system to a newer one, keeping your settings, server roles, and data intact. For example, if your server is running Windows Server R2, you can upgrade it to Windows Server However, not every older operating system has a pathway to every newer one.
Upgrade works best in virtual machines where specific OEM hardware drivers are not needed for a successful upgrade. You can upgrade from an evaluation version of the operating system to a retail version, from an older retail version to a newer version, or, in some cases, from a volume-licensed edition of the operating system to an ordinary retail edition.
