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:
- Checking System Requirements:
Ensuring that your hardware meets the new system requirements for Windows 11.
- Compatibility Checks:
Running any necessary compatibility tools provided by Microsoft to confirm that your existing software and systems are compatible with Windows 11 LTSC.
- Backing Up Data:
Making sure all important data is backed up before attempting an in-place upgrade.
- 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
