migrating from CVS

[Jos Backus]

I'd like to say thanks to everybody answering my questions so far. Migrating
to a new VCS is not a project undertaken lightly so we are trying to be as
well-prepared as possible selecting a suitable successor.

Besides looking at features that distinguish Bazaar-NG from CVS/Subversion, of
importance to us is a sense of how "production-ready" Bazaar-NG is.

In particular:
- Stability of the storage/repository format. Having to make disruptive
  changes to repositories would be a bad thing, and I'm happy to see that that
  the release roadmap says that the storage format should remain stable for
  the next year after 0.8 is released. Are any other major repository format
  changes being planned the would potentially impact production sites?

- Size of the source code base Bazaar-NG can handle reliably without slowing
  down to a crawl. How safe is it to migrate a CVS repository with a dozen or
  so modules containing thousands of files each? Has Bazaar-NG been tested
  against such large repositories?

Do you think Bazaar-Ng is ready for this type of (heavy) use, replacing CVS?
Or would we at this time be better off switching to Subversion (even though
its featureset is limited by comparison)? Or alternatively, would you say that
Bazaar-NG isn't quite there yet but wil be soon, so we should hold off (a few
more months) if we can?

I realize these are difficult questions and ultimately nobody else but us can
make the decision. But your opinions are very valuable nontheless. Comments
appreciated.
