Upgrades

Control Plane Upgrade

Upgrading the OpenShift version of the control plane is supported by the provider. To perform an upgrade you need to update the version in the spec of the ROSAControlPlane. Once the version has changed the provider will handle the upgrade for you.

Upgrading y-stream version ex; v4.16.x to v4.17.x required the version gate acknowledgement. By default the versionGate is set to WaitForAcknowledge in the ROSAControlPlane CR. When upgrading to y-stream version the versionGate should be set to Acknowledge or AlwaysAcknowledge.

Note:

When the versionGate is set to ‘Acknowledge’, it will revert to ‘WaitForAcknowledge’ once the upgrade is successfully completed. However, if the versionGate is set to ‘AlwaysAcknowledge’, it will remain set to ‘AlwaysAcknowledge’ after the upgrade is successfully completed.
