See what components need to update in what order (requires bower)

It's a WIP. Come bug me for how to use this if you end up needing it.

Install: bashful install https://gist.github.com/kyle-west/720df27659d372e395ec86317f506113
Run: From app, tree or tree-v8-person, migrate-to [package] v[next-major] migrate-to fs-person-data-service v5

Then it spits out the order in which to update all the repos.
