- Upgrading Core or EEP Components
  Depending on your current configuration, you may choose to upgrade the release version (core), ecosystem components, clients, or monitoring components.
  - Upgrade Workflows (Releases 6.x or 7.x to 7.7.0)
    This section describes three common methods for upgrading from one core release to another. The workflows in this section introduce you to the high-level steps for each method and provide links to pages showing more detail.
  - Upgrading Core
    Describes the process of upgrading core.
  - 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.
    - Planning 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 Ecosystem Pack
      Complete these pre-upgrade steps for each ecosystem component in the EEP that you want to upgrade.
    - Upgrading the Ecosystem Pack With the Installer
      If the cluster that you want to upgrade was installed using the Installer, you can use the Installer to upgrade the Ecosystem Pack (EEP).
    - Upgrading the Ecosystem Pack Without the Installer
      After you upgrade core without using the Installer, you need to upgrade ecosystem components with manual steps. First, verify that your repository is configured to use an Ecosystem Pack (EEP) that is supported by your cluster version. Then, upgrade each component manually.
