Berkeley DB _ALWAYS_ has backward compatibility in format,
but log format's change nearly every release. Lose the logs
(and __db* files) during upgrade, and the transition should be easy:
        dbXY_checkpoint -1
        dbXY_recover -v
(where XY is the "old" version) before upgrade will save you mucho pain.

(aside from 1st hand experience)
Watch out for db-5.2.19 -> db-5.2.25 however. Someone
at Sunacle had a brain fart that could have been avoided
if anyone had bothered to examine this output:
        http://upstream-tracker.org/versions/libdb.html
before doing a "release".

Smart guys too: several are my current bosses. ;-)

Short answer:
        This URL is incredibly useful:
                http://upstream-tracker.org/
        and not just for Berkeley DB.
