Thread:Project:Support desk/Catecory page's description not showing

MediaWiki	1.22.2 PHP	5.3.27 (cgi-fcgi) MySQL	5.1.67-rel14.3-log

Hi, I export from an old wiki version 1.13.4 all pages and import them to 1.22.2 because I wanted to start from empty database. But I have lost the category pages' description texts. How to move them? You know the text which is written above the page links when open a category.
