Workflow: Manual Rolling Upgrade from Release 6.x or 7.x to 7.9.0

This page summarizes the steps for upgrading from release 6.1.x or 6.2.0 or 7.x to release 7.9.0 by using a manual rolling upgrade. In this workflow, the cluster to be upgraded is secure; after the upgrade, the cluster will continue to be secure.

Manual Rolling Upgrade Summary

In a manual rolling upgrade, you upgrade the software one node at a time so that the cluster as a whole remains operational throughout the process. The manual rolling upgrade requires you to:
  1. Perform pre-upgrade checks.
  2. Perform a rolling upgrade of core.
  3. Verify that all use cases are functional on the cluster.
  4. Upgrade the EEP to 9.3.1.
  5. Merge custom configuration settings.
  6. Enable 7.9.0 features.
  7. Perform post-upgrade checks.

The workflow later in this section provides more detail to help you get started with a manual rolling upgrade.

Considerations for Manual Rolling Upgrades

Before performing a manual rolling upgrade, note these considerations:
  • Rolling upgrades only upgrade core packages, not ecosystem components. A rolling upgrade of ecosystem components is not supported.
  • If you choose to do a rolling upgrade on a cluster with core and ecosystem components, the ecosystem components will continue to work during the rolling upgrade as long as the ecosystem components are not updated. If you choose to upgrade core and ecosystem components together, the ecosystem components might not function properly during the upgrade process.
  • After upgrading core to release 7.9.0, you must upgrade ecosystem components to EEP 9.3.1 or later, and this must be done before you enable 7.9.0 features.

This page includes the steps to generate Object Store certificates by using manageSSLKeys.sh. The certificates must be generated after upgrading and running configure.sh -R. If you fail to generate the certificates, you will not be able to use the Object Store.
