Need to Merge the new users with the old users. Our mediawiki is based on the folowing configuration MediaWiki 	1.21.2 PHP 	5.3.27 (cgi-fcgi) MySQL 	5.5.32

Tried the plugin Merge and Delete, but it does not work. I have around 4 lakh records that needs to be merged. Is there any utility that can be used to perform this?
