Little code has been written at hackathons in the past so it would
need to have a bit of a different format.

Or we just divvy up the work (I could do the migration of .META. and
-ROOT- to pb and of zk persistence to pb if wanted).

Phase 2 seems just as bad as a disruption as phase 1 or am I reading
it wrong; i.e. its another singularity that can't be crossed w/o a
restart of all servers.

I suppose I'm wondering if we think we can nail phase 1 and phase 2
within a single release cycle; then the two singularities are
experienced as one during a single upgrade.
