Hey MB - good question. Its not about "premium" solution its about evolution. IWAN was introduced to the market almost 3 years ago. That's an eon considering how fast the market is moving.

We were already planning and developing a Next Gen release to address these new realities. In addition we want to make several changes in technology architecture to set us up for the long term. This included a new fabric overlay and path control. Viptela helps us accelerate the introduction of this next gen tremendously.

So in that context its a new release of our SD-WAN solution train.
We had IWAN 1, IWAN 2 and now our Next Gen - all part of the evolution.

We will continue to support customers on our IWAN 2 release and the roadmap there will overlap our next gen. Choice of which one will depend on your use cases, platform investments and deployment timelines but if your just starting out, we'd recommend to be looking at the next gen release.
