[ovirt-users] Failure while import VM from export domain

Hi oVirt list, I'm planing to migrate my oVirt installation on a new HW. My current platform is running a 4.2.8. The new one a 4.3.5. I'm currently trying to import the VMs through the export domain. But some of my old VMs are failing. Which log file would be interesting to check? Also maybe there is a better way to copy more less all VMs from my current oVirt to the new one. Best regards Christoph
