Migrating host to v2 took a really long time (like 10 hours)

I just upgraded to hostd 2.1.0 and wow, it took about 10 or so hours to complete the migration. Don't have the exact time because I needed to let it finish overnight, and then it was up and running when I woke up.

I don't have a point, per se, just heads up for anyone who has yet to do it and wants to schedule their downtime.
