I just uploaded a copy of my current insurance, no vin for the new Y. I believe, at least if you're in California, you have some leeway with the insurance.
Actually, this is what Tesla says:
Proof of insurance is required to take delivery, and must be valid for the next 60-90 days. If you're registering in these 12 states, insurance can be provided for an existing car. In all other states, insurance must be provided for the Model Y.
