If I understand you well, you mean that new Gnatsweb should still allow work with GNATS 3? This would be nice but it is solely a matter of Gnatsweb. If Gnatsweb is designed well enough, the backward compatibility shouldn't be a big problem. (As for my gnats2w hack, there's no problem with retaining the backward compatibility with GNATS 3, there is a problem with supporting the full flexibility of GNATS 4 instead -- gnats2w wasn't designed with a big functional extensions of the server in mind.)

Yes, moving databases should be easy -- actually I use a copy of GNATS bug database from sources.redhat.com (running with GNATS 3 there) on my machine with GNATS 4. All I had to do was to add the `dbconfig' file and to customize it a little. Of course, I plan to document the upgrade process appropriately.
