[ovirt-users] Need advice before building a new oVirt Environment

My question will be down below but before that here is some background info: I currently have a functioning oVirt env (v4.5.7) with two self-hosted nodes (hand-me-down servers) and shared storage (TrueNAS server) with three data domains: one for the EngineVM (iSCSI), one for the VMs (iSCSI) and one for ISO files (NFS). The powers that be, want to move away from TrueNAS and hand-me-downs and have new servers and a new NAS appliance (most likely NetApp). They are the ones who did not want to spend the money on new gear but now they have changed their minds. I wish that I could have started my oVirt env on the new equipment. This new equipment will take at best 2 months to arrive. In the meantime, I have to create various VMs in my existing environment. Once my new gear arrives, what is the recommended approach: 1 - Start from scratch with a new datacenter/cluster env? Can I migrate VMs from one DC to another? The docs seem to say no. I'm guessing, I would have to export first, then import. 2 - Can my new equipment be part of the same DC but a different cluster? I was thinking that option #2 is the right approach. I could start with storage (ie: new NetApp) as part of the new cluster. Once that is part of the cluster, I can add hosts then finally migrate VMs. What say you? thank you in advance.
