[ovirt-users] Do we have to update ovirt to import storage domain?

Hi, We have a test environment build on ovirt 3.5 and now we have installed a new platform build on ovirt 4.1 and we want to import the test VMs into it. The question : do we have to update the test environment to be able to import the vms? If yes, to what version do we have to update? The minimum version needed Regards
