Hi all, I'm starting to transfer a mediawiki 1.7 database in new version mediawiki 1.13.1 I look that there are new tables and any fields are lightly changed. I think that I can not use old database (about mediawiki 1.7 version).. so Is there script/other to convert old database (about mediawiki 1.7 version) to new database (about mediawiki 1.13.1 version) ? Can you help me about it? Thanks,

See http://www.mediawiki.org/wiki/Manual:Upgrading It usually involves copying the new files over the previous and run the update.php script at the maintenance folder.
