Upgrading Data Fabric Software

This section describes the process of upgrading core, the ecosystem components, and the Data Fabric clients.

Upgrading core usually means you need to upgrade the Ecosystem Pack (EEP). For example, upgrading to release 7.9 requires you to upgrade to EEP 9.3.1 or later before you can enable release 7.9 features.

The steps for upgrading an EEP are in another section of this guide because EEPs can be upgraded independently of the core version. The following procedures prompt you when it is necessary to plan for or upgrade an EEP.

Upgrading core consists of the following steps:

Planning the Upgrade – Determine the upgrade method, when to upgrade, and whether ecosystem components or Data Fabric clients need to be upgraded along with core.
Preparing to Upgrade – Prepare the cluster for upgrade while it is still operational. This includes pre-upgrade steps for core and ecosystem components.
Upgrading the Cluster
- Upgrading with the Installer - The Installer provides a web interface that automates the upgrade of core and ecosystem components.
- Upgrading without the Installer - You can perform manual steps to upgrade core and manually upgrade each ecosystem component.
Finishing the Upgrade - You complete the post-upgrade steps for core and any ecosystem components that you upgraded.
Upgrading Data Fabricclients – You perform steps to upgrade the Data Fabric clients.

NOTE

In this document, the existing version refers to the release version that you are upgrading from and the new version refers to the release version that you are upgrading to.
