[ovirt-users] migrating standalone engine to selfhosted and upgrade from 4.3 to 4.4 in one step

Hello, I have 4 host cluster managed with standalone engine in version 4.3 and I would like to migrate this standalone engine to 4.4 as hosted engine. I have two new hosts which I would like to use as base for new HE cluster. (new hosts are Intel based, old ones are AMD Opteron based - new cluster will have 4.4 compatibility, old one have to stay at 4.2 compatibility level). I red this https://www.ovirt.org/documentation/migrating_from_a_standalone_manager_to_a... but the question is: Can I migrate and upgrade in one step? Have anybody did that already? If it is not possible what is a suggested approach? Thanks for help Jiri
