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. To get started, check the server role upgrade and migration matrix for Windows Server. This feature allows you to avoid downtime which could impact Service Level Agreements.

This new feature is discussed in more detail at Cluster operating system rolling upgrade. License Conversion In some operating system releases, you can convert a particular edition of the release to another edition of the same release in a single step with a simple command and the appropriate license key. 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. Upgrade If you want to keep the same hardware and all the server roles you have set up without flattening the server, upgrading is an option—and there are lots of ways to do it.

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. 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.

Before you get started with an upgrade, have a look at the tables on this page to see how to get from where you are to where you want to be. For information about the differences between the installation options available for Windows Server Technical Preview, including the features that are installed with each option and the management options available after installation, see Windows Server NOTE] Whenever you migrate or upgrade to any version of Windows Server, you should review and understand the support lifecycle policy and timeframe for that version and plan accordingly.

You can search for the lifecycle information for the particular Windows Server release that you are interested in.
