OVH did migrate all its regions from Juno to Newton, you should be able
to find presentations on that from past summits videos.
Similarly, Verizon media / Oath did migrate from Juno to Ocata. James
Penick did presentations and some blog articles about it.
But yes, as others said, that would certainly not be the first upgrade I
ever attempted. Juno pre-dates most of the work on simplifying upgrades,
so it's a painful starting point.
