    You can and should.

    Note however:

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

    When upgrading Exchange from an unsupported CU to the current CU and no intermediate CUs are available, you should first upgrade to the latest version of .NET that's supported by Exchange and then immediately upgrade to the current CU. This method doesn't replace the need to keep your Exchange servers up to date and on the latest supported CU. Microsoft makes no claim that an upgrade failure will not occur using this method, which may result in the need to contact Microsoft Support Services.

  • Yes, you can upgrade directly, You would probably need to upgrade your .NET framework & VC++ to versions supported by the latest Exchange CU as the older CU would have older versions.

  • Please note: Exchange 2016 CU10 and onwards will require the VC++ 2013 runtime library installed on the server.

    So, you should install VC++ 2013, then you will could update Exchange from CU 5 to Cu 12/13 directly.
