[Labs-l] Migrations beginning again, starting today

[Ryan Lane]

We've found a safe method for doing migrations. The only downside is
that it's a cold migration, which will result in a reboot of the
instance. That said, this migration method is actually much faster
than the old migration method, so it may result in less downtime
overall.

We'll be beginning migrations today, and will likely do them fairly
slowly. I expect them to be finished in 1-2 weeks.
