Thread:Project:Support desk/MediaWiki Upgrade from 1.16.2 to 1.25

Hi, I am struggling to update our MediaWiki from 1.16.2 to 1.25. The current version 1.16.2 works on a WindowsXP machine. This machine will be as next shutdown, because of old operating system. I've installed the new Bitnami Mediawiki Stack 1.25 at a new machine, which has WindowsServer2008R2. I did DB backup and then XML backup at the old machine with the following scripts: mysqldump.exe bitnami_mediawiki -u root -p --result-file=C:\Wiki_BAK\bitnami_mediawiki.mysql php dumpBackup.php --full --output=file:C:WiKi_BAK\xml_dump.xml I was able to restore the MySQL-backup at the new machine without error. However, I could not import the XML files. Used script: php importDump.php < xml_dump.xml Resulting error: A database query error has occurred. Query: SELECT page_id,page_len,page_is_redirect,page_latest,page_content_model FROM `page` WHERE page_namespace = '0 ' AND page_title = 'Main_Page' LIMIT 1 Function: LinkCache::addLinkObj Error: 1054 Unknown column 'page_content_model' in 'field list' (127.0.0.1:3306)

I'd be pleased, if someone can help me further. Thanks in advance, Murat
