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,

hosted-engine --upgrade-appliance is designed specifically for 3.6 -> 4.0 upgrade where you are supposed to upgrade the OS of the engine VM from el6 to el7.
It's not needed for other upgrades.

Please follow this guide:

Thanks
John
