Perform an in-place upgrade of Windows Server

An in-place upgrade allows you to go from an older operating system to a newer one while keeping your settings, server roles, and data intact. This article will teach you how to move to a later version of Windows Server using an in-place upgrade.

Before you start upgrading, your computer must meet the following requirements:

Collect diagnostic information

We recommend that you collect some information from your devices for diagnostic and troubleshooting purposes in case the upgrade is unsuccessful. We also recommend you store the information somewhere you can get to even if you can't access your device.

To collect your information:

  1. Open an elevated PowerShell prompt, make a note of your current directory, and run the following commands.

    Get-ComputerInfo -Property WindowsBuildLabEx,WindowsEditionID | Out-File -FilePath .\computerinfo.txt
    systeminfo.exe | Out-File -FilePath systeminfo.txt
    ipconfig /all | Out-File -FilePath ipconfig.txt
  2. Using File Explorer, navigate to the directory you noted down, and copy the files to a USB flash drive or network location off of your computer.


Get-ComputerInfo requires PowerShell 5.1 or later. If your Windows Server version doesn't include Powershell you can find this information in the registry. Open Registry Editor, go to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion key, and then copy and paste the Windows Server BuildLabEx and EditionID values.

After you've collected all of your Windows Server-related information, we recommend that you backup your server operating system, apps, and virtual machines. You must also shut down, quick migrate, or live migrate any virtual machines currently running on the server. You can't have any virtual machines running during the in-place upgrade.

Perform the upgrade

Now you've completed your prerequisites and collected diagnostic information, you're ready to perform the upgrade. In this section, you'll use the Windows Server Setup to select the settings for the upgrade. Windows Server Setup will use these settings to upgrade your version of Windows Server, during which time your computer will restart several times.

To perform the in-place upgrade:

  1. Using File Explorer, navigate to the Windows Server Setup media. Then open setup.exe. For example, if you're using removal media the file path might be D:\setup.exe.


    Depending on your security settings, User Account Control may prompt you to allow setup to make changes to your device. If you're happy to continue select Yes.

  2. By default, setup will automatically download updates for the installation. If you're okay with the default settings, to continue select Next.

    If you don't want Setup to automatically download updates:

    • Select Change how Setup downloads updates, choose the option appropriate to your environment, then select Next.
  3. If prompted, enter your product key, then select Next.

  4. Select the edition of Windows Server you want to install, then select Next.

  5. Review the applicable notices and license terms, if you agree to the terms, select Accept.

  6. Select Keep personal files and apps to choose to do an in-place upgrade, then select Next.

  7. After Setup finishes analyzing your device, setup will display the Ready to install screen, to continue the upgrade select Install.

The in-place upgrade will start, and you should see a progress bar. After the upgrade finishes, your server will restart.

Checking if your upgrade was successful

After the upgrade to Windows Server is done, you must make sure the upgrade was successful.

To make sure your upgrade was successful:

  1. Open an elevated PowerShell prompt, run the following command to verify the version and edition matches the media and values you selected during setup.

    Get-ComputerInfo -Property WindowsProductName
  2. Make sure all of your applications are running and that your client connections to the applications are successful.

If your computer isn't working as expected after the upgrade, you can contact Microsoft Support for technical assistance.
