    - Planning Ezmeral Ecosystem Pack (EEP) Upgrades
      The set of ecosystem components that you run in the cluster must all belong to the same EEP.
    - Preparing to Upgrade the Ezmeral Ecosystem Pack

    - Upgrading the Ezmeral Ecosystem Pack Without the MapR Installer
      After you upgrade MapR core without using the MapR Installer, you need to upgrade ecosystem components with manual steps. First, verify that your repository is configured to use an Ezmeral Ecosystem Pack (EEP) that is supported by your cluster version. Then, upgrade each component manually.
