    I have an Exchange 2013 SP1 server that is behind on Cu updates.

    The only ones available to download are Cu21 and Cu22.

    My question is is there any other prerequisites that need to be done before they're installed?

    Any known issues going from an older Cu to the latest Cu?

    Do I just run the Cu exe or do I need to use CMD or powershell with additional information?

    Hi,

    As per my knowledge, There is no issues for latest CU's(CU21 &22).

    You should be need to ensure what is .net version using in Exchange 2013 SP1 in your environment.

    If .NET Framework 4.6.2 or lower version using, you need to be upgraded supported version.

    Finally you can use any type of installation like GUI/CUI.

    Refer:https://docs.microsoft.com/en-us/exchange/plan-and-deploy/supportability-matrix?view=exchserver-2019

    Hi,

    There are some points you must pay attention to before upgrade:

    1. Double check the prerequisites for the setup of Exchange Server 2013. For your reference:Exchange 2013 prerequisites
    2. Require Microsoft .NET Framework 4.7.1.
    3. Need install Visual C++ Redistributable Packages for Visual Studio 2013.
    4. Use the following command to prepare AD:
    \Setup.exe /IAcceptExchangeServerLicenseTerms /PrepareAD

    Thanks for the reply.

    It worked in a test environment.

    I'll be running it in my live environment later this month.
