As long as new version can read old repos reliably, new repos can represent a superset of the old metadata, and there's a conversion utility, this is not a problem. Generic database managers deal with these problems all the time, it's "solved" in some sense. Question in my mind is, given bzr's propensity to change representations, does the bzr development team have somebody who's worked on that kind of function, and demands that functionality be rock-solid?
