Windows Server 2008 R2 is approaching the end of its support lifecycle. This means that as of January 14, 2020[^3^], there will be no additional free security updates, non-security updates, or free support options for the operating system. Users who want to continue receiving updates and support for Windows Server 2008 R2 will need to upgrade to a newer version of Windows Server or migrate to a cloud-based solution.One of the options for users who want to keep using Windows Server 2008 R2 is to upgrade to a newer version of Windows Server. This can be done by performing an in-place upgrade, which replaces the existing operating system with a new one without affecting the applications, data, and settings. However, an in-place upgrade has some limitations and requirements that need to be considered before starting the process.
Some of the steps and considerations for upgrading Windows Server 2008 R2 are:
Check the compatibility of the hardware, software, and roles with the target version of Windows Server. Some roles and features may not be supported or may require additional steps to migrate. For example, if the server is an Active Directory domain controller, you cannot convert it to a retail version[^1^]. You can use tools such as the Microsoft Assessment and Planning Toolkit (MAP) and the Windows Server Upgrade Center to help you with the compatibility assessment.
Back up your server and data before starting the upgrade. This will allow you to restore your system in case of any issues or failures during the upgrade process.
Disable or uninstall any third-party software that may interfere with the upgrade, such as antivirus, backup, or encryption software.
If your server uses NIC Teaming, disable it prior to upgrade, and then re-enable it after upgrade is complete[^1^].
Locate the setup media for the target version of Windows Server and start the setup.exe file. If your server is connected to the internet, make sure you select Go online to install updates now (recommended) to download the latest updates to the installer[^2^].
Choose the edition of Windows Server that you want to install and accept the license terms. You can only change from Standard edition to Datacenter edition when upgrading. Changing from Datacenter edition to Standard edition is not supported[^1^].
Select Upgrade: Install Windows and keep files, settings, and applications. This option will preserve your existing data and applications.
Follow the instructions on the screen to complete the upgrade process. The server may restart several times during the upgrade.
After the upgrade is complete, you can activate Windows Server with a valid product key or a digital license. You can also check for any post-upgrade tasks or issues that may need your attention. 0efd9a6b88
