Thanks for all the great discussion and advice!

I am planning ahead for this expansion of space.  We need it badly but
not so badly that we want to rush and risk data!  I was going to do it
on Saturday but that's Phoenix Bar Camp[1] so maybe the Saturday after
that.  Or a long, late night this week.

The best advice I had not thought of was to test it.  Duh!  I'll be
doing a test first to make sure I'm good with the process.
