Upgrading Veeam Kasten

Note

Currently, upgrades are only supported across a maximum of four versions (e.g., 2.0.10 -> 2.0.14). If your Veeam Kasten version is further behind the latest, a step upgrade process is recommended where you can use the [--version] flag with helm upgrade to control the version jumps. At least 50% free space is required in catalog storage also.

Upgrade Assistant

You can verify the available free space for the catalog and access your recommended upgrade path by navigating to the System Information page from the Settings menu in the navigation sidebar or by using Veeam Kasten Primer for Upgrades resource.

Upgrading an Operator Installed Veeam Kasten

Upgrading a Veeam Kasten installation made by a Veeam Kasten Operator requires updating the Veeam Kasten Operator. Ref: Red Hat documentation for upgrading installed Operators.

The process of upgrading the Veeam Kasten Operator depends on how update was configured during install - Automatic or Manual.

The Operator update approval strategy can be changed anytime after install from the Subscription tab of the Operator.

For an Automatic update, the Veeam Kasten Operator and Operand (which is the Veeam Kasten install) are both automatically updated any time a new Veeam Kasten Operator is published.

For a Manual update, the cluster administrator must approve the update when it shows up for the installation to begin. Ref: Red Hat documentation for manually approving a pending Operator upgrade.

The Veeam Kasten operators are published with a maximum supported OpenShift version. This will cause warnings to appear when trying to upgrade a cluster beyond the maximum supported version.

warning

Upgrading the cluster beyond the Veeam Kasten maximum supported OpenShift version may cause unpredictable Veeam Kasten behavior and will result in losing Kasten support.
