[ovirt-users] migrate to Hosted engine set up using ovirt node 3.6

Hi I am in the process of upgrading my ovirt DC to 3.6. I would like to migrate to hosted-engine with gluster replica 3 storage in the process. The engine has been upgraded and I have installed 3 of the VM hosts in one cluster using the ovirt-node iso. I have three other VM hosts in a separate cluster to upgrade. I see an option to configure the hosted engine through the node admin login tui, however I have not found any up to date instructions on how to perform a migration to hosted using the ovirt-node. I thought I'd ask a few questions before I started: Should I connect and approve the node in the current engine prior to configuring the hosted engine? Does the node hosted-engine-setup provide a pause to restore the engine db from the external engine? Or even better a facility to upload the database backup file? Any feedback gratefully received. Thanks, Alastair
