So I had a mediawiki installed on windows with MySQL (running on AWS RDS). I've since moved it to a debian server for various reasons, but I think I've messed up the database because of the different versions of mediawiki I have used.

The windows install was v 1.20alpha (58f390e). The new debian install is v 1.15.5-2squeeze4.

I've tried to update debian but it doesn't find an update, so is this the latest squeeze version?

Everything seems to work ok except adding users. It gives me a database error so I ran php maintenance/update.php which ran some stuff OK but didn't make a difference. I think I've not done the correct approach to this sort of move, does anyone know of a better way of doing it? I still have the old wiki running - but not used - on windows (using the same database) so I could always try this again.

The simple fact is almost no web-apps are design to handle a down-grade. Once a database has been updated, you usually can never go to an older version without causing problems.

I don't know much specifics about mediwiki, but my guess is that you have two choices.

  • Remove the packaged version of mediawiki you found on your Debian system, and you need to manually re-install, using the same version or newer version then what you were running.
  • Or simply, or not so simply, manually migrate/rebuild the entire site on the older version.

I think the best thing then is to wait for the debian version to be upgraded or to rebuild the whole thing. – ing0 Oct 28 '12 at 10:21
Waiting for the Debian package is probably a bad idea. Since it won't be updated until wheezy is released next year. – Zoredache Oct 28 '12 at 17:44
I ended up rebuilding the database. I've learnt not to switch os's with this kinda software! – ing0 Dec 22 '12 at 0:58
