MediaWiki is at least theoretically able to upgrade
its database schema
from any old version to current one for your chosen version, by running
the maintenance/update.php script.
The issue is that any recent Mediawiki requires MySQL5+. But MySQL5+
can't read a dump from the old wiki, even with some edit of deprecated
commands (like TYPE to ENGINE), handling of too long keys, there's
always another error, always something more.
So it's seems to be a vicious circle. I can't upgrade MW because of
MySQL, and I can't upgrade MySQL because the database scheme updates are
Any way around that, without being a sql guru? Should an intermediary
upgrade to MW 1.8 resolves this?
