This looks nice! Having a smooth LFS experience in GEI would be very beneficial to a bunch of the customers I work with.

@roferg What is needed to get this merged?

@robandpdx - I'm actually rolling off being the migrations PM and onto another project. @timrogers will be the new PM for migrations moving forward. You should work with him and @dylan-smith to get this over the finish line. Note, @dylan-smith is OOO this week and will be back next week.

Closing this because it's super stale. If the team decides to pick it back up we can always re-open.
