Hi All, My organization currently has Windows 10 LTSC 1809 & 21H2 OS for client machine. We are planning to upgrade to Windows 11 LTSC 24H2 via in-place upgrade. I would like to know if this can be done. I heard for LTSC 1809 cannot be in-place upgrade.

Cheers,

Sim Bin

    Hello Sim Bin (NCS),

    Thank you for posting in Q&A forum.

    I am sorry, after a lot of my search, I cannot find the Windows LTSC official upgrade instructions.

    However, you will need to follow their specific guidelines for upgrading. This typically involves:

    1. Checking System Requirements:

    Ensuring that your hardware meets the new system requirements for Windows 11.

    1. Compatibility Checks:

    Running any necessary compatibility tools provided by Microsoft to confirm that your existing software and systems are compatible with Windows 11 LTSC.

    1. Backing Up Data:

    Making sure all important data is backed up before attempting an in-place upgrade.

    1. Following Upgrade Paths:

    Adhering to Microsoft's recommended upgrade paths, which will likely be detailed in their release notes or upgrade documentation.

    You may need to do a clean install instead of a direct upgrade, and you'll need to see if your license agreement covers the new version. If you can perform the in-place upgrade from lower LTSC to higher LTSC version, upgrading to a new version of LTSC usually requires the purchase of a new product key.

    I hope the information above is helpful.

    If you have any questions or concerns, please feel free to let us know.

    Best Regards,

    Daisy Zhou
