On the cloud, it is likely simpler and faster to just spin up a new cassandra datacenter, and then do a rebuild from the old datacenter to the new datacenter, either all nodes at once in parallel or in smaller batches. This procedure works fine regardless of using static tokens allocation or vnodes, and adds very little load to the old datacenter which is still serving traffic.
