    This section describes the process of upgrading core, the ecosystem components, and the Data Fabric clients.
    - Upgrading and Your License
      You do not need a new license to upgrade an HPE Ezmeral Data Fabric cluster. However, it's a good idea to check your cluster license periodically and renew the license before it expires.
    - Core Upgrade Process
      When you upgrade core, you will also upgrade a number of cluster components.
    - Planning Your Core Upgrade
      Describes how to develop a successful plan for your upgrade process.
    - Securing the Cluster Before Upgrading
      If the cluster to be upgraded is nonsecure, you must secure it before upgrading.
    - When Upgrading Core with the Installer Requires an OS Upgrade
      Helps you decide if an OS upgrade is needed when you are using the Installer to upgrade to core 7.0.0 or later.
    - Upgrading Your Linux Operating System
      Upgrading to a new release of the HPE Ezmeral Data Fabric sometimes requires you to upgrade your Linux operating system. This page has pointers to more information about OS upgrades.
    - Preparing to Upgrade Core
      Complete these pre-upgrade steps for core.
    - Upgrading Core With the Installer
      If the cluster that you want to upgrade was installed using the Installer, use the Installer to upgrade core.
    - Upgrading Core Without the Installer
      You can upgrade core without using the Installer.
    - Finishing the Core Upgrade
      This section provides post-upgrade steps for core.
      - Post-Upgrade Steps for Core
        After upgrading core, several manual steps are required.
        Considerations for Upgrades Using the Installer
        If you use the Installer to upgrade the cluster, some post-upgrade steps for core do not need to be performed. This page describes the post-upgrade steps that are performed by the Installer and the steps that you must perform manually.
        Step 1: Restart and Check Cluster Services
        After upgrading core using either a manual offline or rolling upgrade method (not upgrading with the Installer) and upgrading your ecosystem components, configure and restart the cluster and services.
        Step 2: Manually Update Configuration Files
        After upgrading core using a manual offline or rolling upgrade method, update your configuration files.
        Step 3: Upgrade Clients
        After you upgrade your cluster, you may also need to upgrade your data-fabric client or POSIX client.
        Upgrading the Data Fabric Client
        Depending on which Data Fabric client you want to update, you will either need to install and reconfigure or perform a package upgrade.
        Upgrading the Data Fabric Client on a Linux Server
        This section describes how to upgrade the Data Fabric client on a Linux Server.
        Upgrading the Data Fabric Client on Windows
        This section describes how to upgrade the data-fabric client on Windows.
        Upgrading the Data Fabric Client in Mac OS X
        This section describes how to upgrade the Data Fabric client on Mac OS X.
        Upgrading the Data Fabric POSIX loopbacknfs Client
        Perform a package upgrade to get a newer version of the data-fabric POSIX loopbacknfs Client.
        Upgrading the FUSE POSIX Client on a Linux Server
        This section describes how to upgrade the FUSE POSIX client on a Linux server.
        Step 4: Enable New Features
        Describes the new features to enable after upgrading core without the Installer using a manual offline or rolling upgrade method.
      - Installing Additional Core Features
        Some features can require additional configuration or the installation of additional packages after an upgrade to a new release.
  - Upgrading Ecosystem Packs
    Describes how to upgrade Ecosystem Packs (EEPs), either as part of a core upgrade or to take advantage of a new EEP for the current version of core.
  - Preparing the Cluster for a Maintenance Update
    This section identifies how to prepare for applying either a minor update or a patch.
  - Performing a Maintenance Update
    Perform a maintenance update when you want to upgrade to a new patch version of core or apply a patch.
- Setting Up Clients and Services
  Describes how to set up and use interfaces to an HPE Ezmeral Data Fabric cluster from a client computer.

Upgrading the Data Fabric Client on Windows

This section describes how to upgrade the data-fabric client on Windows.

About this task

When you upgrade the data-fabric client on Windows, you need to rename the existing client directory, install the new version, and then merge the configuration files.

Procedure

Rename the existing client installation directory. For example, you can rename \opt\mapr to \opt_old\mapr.
Complete the installation steps in Installing the Data Fabric Client on Windows (Non-FIPS).
To retain existing configurations and accept new defaults, merge the contents of the directory in the previous installation with the directory in the new installation. For example:
- Previous installation directory: %MAPR_HOME%\hadoop\hadoop-2.x.x\etc\hadoop
- New installation directory: %MAPR_HOME%\hadoop\hadoop-3.3.4\etc\hadoop
