Hello,

I'm currently running Exchange 2019 CU7 and planning to upgrade. Please provide suggestion whether to upgrade to CU8 or CU9 and also does it require any AD changes.

Thank you.

    Hi @Exchange_Newbie ,

    Microsoft recommendation is to install the latest cumulative updates. However, it also depends on the organization and can go either latest or 1 less than the latest CU i.e. N or N-1

    For AD changes, yes. You need to run the below before upgrading,

    setup.exe /prepareschema /IAcceptExchangeServerLicenseTerms
    setup.exe /prepareAD/IAcceptExchangeServerLicenseTerms
