[ovirt-users] Upgrading Hosted Engine version not supported by upgrade flow

Hello, While trying to upgrade a hosted engine to most recent 4.2.4 version, I'm receiving this error "Cluster INT-cluster is at a version 4.2 which is not supported by this upgrade flow. Please fix it before upgrading." I am unable to find a method of fixing the version. The software version on this engine is at 4.2.0.2-1el7.centos. And was installed from the ovirt-engine-appliance rpm. The host boxes are running Centos 7.4 I see this from ovirt-hosted-engine-setup log "DEDUG otopi.context._executeMethod:135 condition False INFO otopi.context.runSequence:735 Stage: Termination" Any guidance would be greatly appreciated, Thanks John
