[ovirt-users] oVirt virtual machines migration 3.6.3 to 4.4.5

Hello, We have a project to migrate from an old oVirt infrastructure (3.6.3) to a new one (4.4.5). The new infrastructure is already in place and we want to migrate the virtual machines. We tried to import the virtual machines via a domain with an NFS mount from the old oVirt (import pre-configured domain). With this domain we only see VM disks and not full virtual machines for import. Is there a way to transfer the virtual machines from the old oVirt to the new one by an NFS mount then import into oVirt Engine or a "copy/paste" virtual machine files then import. Thanks a lot, JMP
