Description of problem: One additional step for each service is required to remove the Data Warehouse and/or Reports services from the original host (when migrating to a new host): # rm -rf /etc/ovirt-engine-dwh # rm -rf /etc/ovirt-engine-reports Didi has added this step (for both DWH and Reports) to the upstream doc [1]. These must be added to the Install Guide [2] too, after the 'yum remove' commands in each topic.
