Transitioning from version 1 to version 2

[Steve Matzura]

I'm wrestling with transitioning from a 1.0.15 system to a 2.2.25
system. The old dovecot.conf cannot be dropped into position on the
new system because so many config options and symbols have changed. It
seems every time I change something to match the new formats, I break
something else! Anyone out there have maybe half an hour to spare to
look at my old and new files to help me whip them into shape?
