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.
