I think the instructions for upgrading Phoenix are pretty much second to none, I just upgraded everything to support the new components system and it is much better than templates because you can have component level state and encapsulation of pieces of your frontend architecture in a React style. It was a pain though you are right! You can also reuse things between normal and live view pages if you break down your components carefully.
I always just look at the number of bugs phoenix has compared to comparable frameworks and it makes me very glad to be using something this stable.
