Migrate Joomla to WordPress links problem

Hello, i’m trying to migrate joomla to wordpress.

I have wordpress 4.3 and Joomla 2.5.

I’m using plugin “FG Joomla to WordPress”.

Transported articles from joomla to wordpress with the plugin, but there is a problem with the links .. ie joomla links are “http://www.test.com/news/world/251481-cnn-criteria-threatens-fiorinas-chance -at-main-debate-stage” and wordpress links after migration looks like” http://www.test.com/cnn-criteria-threatens-fiorinas-chance-at-main-debate-stage”.

What can I do about this? Is there a solution? Because if not corrected will lose all the backlinks but also the links in the search engines..

Thanks in advanced
