All good advice.  Just wanted to add a couple of hints which I found
useful when doing the same job:

Take advantage of the more modular configuration design in 2.1.12,
adding your non-global site specific changes as new files instead of
editing existing files.  This simplifies integration of new defaults on
upgrades, and makes it really easy to roll back to a clean default if
you mess up.

And, as you are going to start from scratch here anyway, I'd also
recommend putting all changed files under revision control.  Don't you
just wish you had that for the 1.1.3 config you've inherited?  Doesn't
need to be anything fancy.  RCS will do.
