Considerations for Downgrading to Kubernetes Operator 5.6.1
Downgrading to Kubernetes Operator 5.6.1 cannot be performed using helm upgrade without first executing helm uninstall.
If the Operator is accidentally downgraded to 5.6.1 without uninstalling, the only available workaround is to perform a helm uninstall and manually unpairing all host workloads from the PCE using Unpair UI button.
Downgrading to version 5.5.3 or earlier works as expected and does not impose any limitations on using helm upgrade.
This behavior is caused by the coexistence of a new activation implementation on the Kubernetes Operator with the legacy activation implementation on the C-VEN. The new activation method is intentionally disabled by Kubelink in version 5.6.1.
