Integrate Pligg with Drupal

Hi,

I have a Pligg site with a litte community and would like to grow up this site with Drupal.
I wish I could migrate my database from Pligg to Drupal, that is I need to keep the users, the news with the number of votes and the comments.
But I don't know much about php.
Is there a way to integrate Pligg with Drupal ? Has anybody already tried to integrate Pligg and Drupal ?

The Pligg code is opensource http://www.pligg.com

Thanks !
