OVA imports, template or vm, silently fail like with Export Domain imports.

Could it be because of the Cluster compatibility version set to 4.6 on both VM & template I am trying to import? 

On the origin oVirt 4.4.6 DC, before exporting them, I tried to see if I could set them to a lower compatibility version but only 4.6is available

I would like to copy them to oVirt 4.3.7 & 4.3.10 DCs

- I saw that Export Domain is deprecated. I tried exporting the VM & template to an Export Domain anyway but,

after attaching the Export DOmain on my ovirt 4.3.7 DC, both VM and Template imports failed.

The Template import failed immediately without any errors visible in the UI, 

The VM import failed with the message "General command validation failure."

- I tried to do it through a Data Domains as recommended, but:

If created on oVirt 4.4.6, I get a Format V5 DataDomain that my oVirt 4.3.7 refuses to import.

If created first on the oVirt 4.3 DC, I get a Format V4 Domain. But then importing it on the oVirt 4.4 DC, I get the message: "Approving this operation will upgrade the Storage Domain format from 'V4' to 'V5'. Note that you will not be able to attach it back to an older Data Center."

In "Administration > Providers" everything seems supported, from XEN / KVM and even VMware (we have used all three with some success).
However oVirt is the obvious missing option...

I still have to try "Export as OVA",
is that the only supported way?
