  1. Hi Stefan – I just inherited a multi-node 2013 Farm and verified that this farm has SP1 + August 2014 CU installed. I want to install all the available security updates ONLY but I’m not sure if I can just install the the latest PU (April 2019)? Can I install all the security updates en masse? What is the installation order for multiple security updates? Or should I skip some security updates and install only the latest ones? Thank you for your help.


    1. Hi,
      first of all your System is unsupported.
      In order to have a supported Environment you need to have at least April 2018 CU installed (see here for details:

      Regarding your questin: you cannot just install the latest PU. The latest PU is cumulative only for the affected component. SharePoint Server 2013 consists of more than 30 individual components and you would have to install the latest security fix for each component.
      My recommendation would be to install the Uber package of the latest CU instead which contains all the security fixes for all the components plus various other fixes.
