[ovirt-users] HostedEngine Upgrade and Rollback

Hi Everyone, Our HostedEngine is previously running in version 4.3.7 then updated it to 4.3.8. Before the update, we did a full backup of the HE. After a successful update, we're testing to roll it back to the previous backup. The cluster setting has been rolled back but the Hosted version is still 4.3.8. Is there a best way to rollback a HostedEngine after a successful minor update? I've read somewhere that if an upgrade / update is unsuccessful, HostedEngine will be rolled back to the previous version automatically. Thanks in advance.
