We currently have Windows 10 LTSC installed on our PC. We have recently purchased a Windows 11 Enterprise 2024 Upgrade license.

Could you please confirm the correct procedure to upgrade our existing Windows 10 LTSC system to Windows 11 Enterprise LTSC? Additionally, can we use the product key from the Windows 11 Enterprise 2024 Upgrade license to directly activate and upgrade our current Windows 10 LTSC installation?

    hi Sathish, Upgrading directly from Windows 10 Enterprise LTSC to Windows 11 isn't supported through typical in-place upgrade paths because LTSC editions are designed for long-term support with minimal changes. To move to Windows 11, you’ll need to do a clean installation using Windows 11 installation media and a valid license for a supported edition like Windows 11 Pro or Enterprise.

    Make sure to back up your data before proceeding, as a clean install will erase everything on the drive. Also, verify that your hardware meets the Windows 11 system requirements, especially TPM 2.0 and Secure Boot.
