Thread:Project:Support desk/Easy way to upgrade from version 1.8 to 2.1?/reply (2)

Thank you for your help. OK, what I did was:


 * 1) backup the mysql database
 * 2) backup the old mediawiki directory
 * 3) transfer them to the new VM
 * 4) I then unpacked the old mediawiki directory
 * 5) restored the mysql database to the new mysql system
 * 6) edited the httpd.conf file to create a virtual server to allow access to the mediawiki directory as the root directory of the webserver
 * 7) ran the update script.

Here I encountered an error:

PHP Notice: Undefined index: HTTP_USER_AGENT in /var/www/html/mediawiki/extensions/FCKeditor/fckeditor/fckeditor_php5.php on line 37 PHP Fatal error: Call to undefined function wfLoadExtensionMessages in /var/www/html/mediawiki/extensions/CategoryWatch/CategoryWatch.php on line 239
 * 1) php maintenance/update.php

Any ideas?
