MDT and new ADK

Hello I currently use MDT to deploy Windows 10 x64 LTSC 2019. We are looking to move to 2021 LTSC. I would of course need to upgrade my ADK from the version made for 1809 to the ADK 2004 version. My question is will this be backwards compatible? Will I still be able to deploy 1809 after the upgrade to the new ADK?

    Hi, @Anonymous
    Thank you for posting in Microsoft Q&A forum.

    Yes, the ADK is backwards compatible. You are able to deploy the earlier version of windows 10 with the new ADK.
    Remember to patch the KB4564442 for ADK 2004 to avoid some possible issues.
