Thread:Extension talk:LiquidThreads/Migrate from older installation

Hi,

I want to migrate from an older installation of lqt, namely r46444 from January 2k9.

However, when I svn up my installation, I don't see the old threads. If I set the $wgLiquidThreadsMigrate = true; when opening a talk page, just nothing happens for ages (same if I manually php the migrateDatabase.php)

Can anyone point me to the required procedures?
