  • Hi Chicojrman123,

    From your description, we know you want to update Exchange 2013 from CU 12 to CU 19.

    In Exchange 2013, Microsoft uses Cumulative Update(CU), the new package will contain the old package. So I agree with what Simon.Rech has said, we don’t need to update Exchange one version by on version. About the schema, when we install Exchange, it will be updated automatically.

    We should pay attention to the .NET Framework as Andy David has said. The best way to update Exchange 2013 from CU 12 to CU 19 take the steps below:
    1. Update Exchange 2013 to CU 15.
    2. Update .NET Framework to 4.6.2.
    3. Update Exchange 2013 to CU 19.
    If you have the Exchange 2013 CU 15 package, you take steps above, otherwise, we should update .NET Framework to 4.6.2 firstly(We may cannot to use Exchange CU 12 after updating .NET Framework to 4.6.2), then we can install Exchange CU 19 to update Exchange. 

    Note: Before update Exchange, we’d better make sure it doesn't affect users, this article will be useful to you: https://www.linkedin.com/pulse/20140323025652-86053522-exchange-2013-maintenance-without-user-impact Note: Since the web site is not hosted by Microsoft, the link may change without notice.

  • Thanks everyone for the plethora of information, here is my basic breakdown of upgrades. Last question would be do i upgrade AD schema and what level should it be at before upgrading to CU15 please?

    1. Upgrade AD Schema, currently it is at 69

    2. Update Exchange 2013 to CU 15.

    3. Update .NET Framework to 4.6.2.

    4. Update Exchange 2013 to CU 19.

    Also 

    I cannot find the download link for CU15, as it is not available anymore in the KB.
    The reason for CU15 is the need to update to .net 4.6.2 before updating to CU19.

    There are no schema updates after CU10:

    https://technet.microsoft.com/en-us/library/bb125224(v=exchg.150).aspx

    As I mentioned in my other post, you can go straight to CU19 if CU15 is not avail.

    When upgrading Exchange from an unsupported CU to the current CU and no intermediate CUs are available, you should upgrade to the latest version of .NET that's supported by Exchange first 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.

  • Hi Chicojrman123,

    Check this blog post https://practical365.com/exchange-server/exchange-2013-installing-cumulative-updates/

    You need to install only CU 19, no intermediates CU. Yes, the schema needs to be updated it's mentioned in the post.

  • Hi Chicojrman123

    There is a pre-req for any CU 16 and above that .Net 4.6.2 has to be installed. But .Net 4.6.2 is not support in any CU below 15. Usually you can just do a CU update with out install previous CU but because .Net is required there is a two setup upgrade. The supported way is

    Upgrade to Exchange 2013 CU15

    Once CU 15 is installed then upgrade .Net to 4.6.2

    Then upgrade to Exchange 2013 CU19

  • If you cant locate CU15, you can go straight to CU19 - after you upgrade to .net 4.7.1.
