[OpenAFS] Further TransArc -> OpenAFS musings/planning

I chose your #2 method of moving my DB servers (4), over the course of a few
weeks during the summer of 04.  I believe both methods has merits and I'll
wager you won't have trouble in any case.

The only caveat with method #1 is if you've made some mistake in the
configuration of one DB server, than you've likely made that same mistake in
all your DB servers and none of them will work.  

I would bring down 1 server, replace it with the new, test the
configuration, and then proceed to bring down the remaining machines.  That
way the DB files will automatically be copied to the new replacement server
from the running machines.

It's really quite a simple matter.  Good luck.
