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
