Tim,

No one I know has done a brownfield migration to Kolla.  If someone
figures it out, I'd be happy to write the documentation based upon the
individuals experience.

The Kolla community is also willing to facilitate the work.  Just drop by
the channel and ask any of our friendly cores if they have suggestions.
This is a problem we will have to solve sooner or later, might as well
solve it sooner.
