Basic idea:

1. company,, was in 3 cities in a WAN setup, one Tree, each
office/city in it's own context. The tree was partitioned.

Now,, 1 off the companies will break loose and run their own business
without any connections to the "mothercompany"...

How to approach this the best way.?
In the existing "main-company"... it's fairly straight forward i
guess, more or less simply delete everything regarding this company
that's going away, removing replicas, deleting the context...etc..

But,, what the best approach of making this "new" company keep running
with a minimum off change..??....,,,I mean,, they WILL loose their CA
when it comes to certificates,,etc,, but,, besides that...?,, any
other major obstacles to be seen..??
