Thread:Project:Support desk/Migrating From mediawiki 1.2 to wikimedia,1.16/reply (2)

Did you run the update script after updating 1.2 to 1.16? It should of fixed the tables. The issue you are experiencing is most likely the mySQL changes that happened at 1.5, You could try to upgrade to that then to 1.16. and after that to the Postgres migration.
