    Hi Glenn Maxwell,

    Thank you for posting your question in the Microsoft Q&A forum.

    What’s the detailed Exchange CU version for the iso file do you use to upgrade schema?

    Please notice that the /IAcceptExchangeServerLicenseTerms_DiagnosticDataON or /IAcceptExchangeServerLicenseTerms_DiagnosticDataOFF switch starts to use for Exchange 2019 CU11 or later, and Exchange 2016 CU22 or later version.
