Upgrade

Learn about Upgrading Trilio on OpenShift and Upstream Kubernetes

RedHat OpenShift

OpenShift updates are delivered directly through the Operator Lifecycle Manager framework.

To upgrade from 4.0.x to 5.0.x, the cluster administrator must switch the subscription channel from 4.0.x to 5.0.x via the Subscription tab in the OpenShift Console. Once the channel is updated, the upgrade process will proceed based on the configured approval strategy (automatic or manual).

When installing the Trilio Operator, the cluster admin can specify how to update via an approval strategy - either manual or automatic.

A manual subscription will require manually approving the new update that is available. An automatic subscription will automatically update the application when an update is available.

OpenShift Approval Strategy

Enable/Disable Openshift Console Plugin
