[ovirt-users] Re: deprecating export domain?

Maybe I overlooked the information, but in recent RHVE 4.3 docs the information how to use the export storage domain have been removed and there is no alternative to do so, but to detach a data domain and attach it somewhere else. But how can I move my VMs one by one to a new storage domain on a different datacenter without completely detaching the original storage domain? I don't want to bring down all of my VMs on the old storage domain for import. I want to export and import them one by one. When all VMs are moved to the new data center only then I want to decommission the old data center. What is the rationale to deprecate the export storage and already remove documentation when there seems to be no alternative available?
