Epic Goal:

Ensure that the Kueue operator can be upgraded across releases without disruption to existing workloads or configurations.

Why is this important?

• Cluster administrators expect upgrades to be transparent and non-disruptive.

• Broken or manual upgrades increase operational risk, downtime, and maintenance overhead.

Scenarios

• A cluster administrator upgrades the Kueue operator from version X to version Y without losing running jobs or configuration.

• Existing resources remain valid and functional after the upgrade.

• CRD schema changes are handled automatically via conversion webhook or defaulting logic.
