for normal VMs - as long as the cluster compatibility is the same you can migrate a VM from your el6-only cluster to a new el7-only cluster - from el6 host to el7 host (using the special cross-cluster migration, both clusters need to be set up the same (storage, networks, etc))

Note you can do that only one way from el6 to el7, and in cluster levels 3.5 or 3.6.

Thanks,
