🗒 Tutorial

Details

Administrators of an Oracle Cloud Native Environment deployment are aware that many of the components, such as Kubernetes, are regularly updated. The upgrade process updates these components to the most recent release allowing any new features to become available for users.

This tutorial will show how to upgrade an Oracle Cloud Native Environment Release 1.6 install to Release 1.7.

Note: Please note that Oracle Cloud Native Environment upgrades are incremental and not cumulative. This is due to a limitation from both the Kubernetes and Istio modules which require incremental upgrades.

  • Upgrade an Oracle Cloud Native Environment install from Release 1.6 to Release 1.7.
