March 2020 CU for SharePoint 2013 product family is available for download

The product group released the March 2020 Cumulative Update for the SharePoint 2013 product family.

For March 2020 CU we have full server packages (also known as Uber packages). No other CU is required to fully patch SharePoint.

As this is a common question: Yes, March 2020 CU includes all fixes from March 2020 PU.


Be aware that all Updates for SharePoint 2013 require SharePoint Server 2013 SP1 to be installed first.

Please also have a look at the article that discusses how to properly patch a SharePoint 2013 farm which has Search enabled (see below).

Previous releases of the SharePoint Server 2013 cumulative update included both the executable and the .CAB file in the same self-extracting executable download. Because of the file size, the SharePoint Server 2013 package has been divided into several separate downloads. One contains the executable file, while the others contain the CAB file. All are necessary and must be placed in the same folder to successfully install the update. All are available by clicking the same Hotfix Download Available link in the KB article for the release.

This CU includes all SharePoint 2013 fixes (including all SharePoint 2013 security fixes) released since SP1. The CU does not include SP1. You need to install SP1 before installing this CU.

The KB articles for March 2020 CU should be available at the following locations in a couple of hours:

  • KB 4484278 – SharePoint Foundation 2013 March 2020 CU
  • KB 4484280 – SharePoint Server 2013 March 2020 CU
  • KB 4484279 – Project Server 2013 March 2020 CU
  • There was no fix released for Office Web Apps Server 2013 this month

The Full Server Packages for March 2020 CU are available through the following links:

After installing the fixes you need to run the SharePoint 2013 Products Configuration Wizard on each machine in the farm. If you prefer to run the command line version psconfig.exe ensure to have a look here for the correct Options.

Be aware that the SharePoint Server 2013 CU contains the SharePoint Foundation 2013 CU. And the Project Server 2013 CU also contains the SharePoint Server 2013 CU and SharePoint Foundation 2013 CU.

Please ensure to have a look at the SharePoint Patching Best Practices before applying new fixes.

  1. Hi Stefan, I have a question about the CU update for my 2013SP1. Our SharePoint farm has large content size(>10T with more that 50 content db). Do you have any suggestion about:
    1. How long will it take to update CU for 10T or 1T ? Do you have any real case about this ?
    2. Any advice if we upgrade the large size server farm ?

    Thank you so much!


    1. Hi Jianbing,
      the amount of data is not that relevant for the upgrade time. Most changes affected store procedures and other structural information in the database.
      Each CU adds things that have to be applied. So what influences the update time most is how many CUs you are behind.


      1. We have a farm that is currently patched through November 2019.

        We want to get it up to the same patch level that we have other farms but had an issue with installing the December 2019 patch.

        Do we need to install the Cumulative Updates for each month, or are they truly cumulative so that we can make the jump from November 2019 to March 2020 with only installing March 2020 CU


        1. Hi Mark,
          they are truely cumulative. You only have to install the Uber package (those patches listed in my blog) for the most current month and you get all patches since SP1 installed.
