Drupal content migration

Hi:

I am trying to migrate a site from Drupal to Elgg. I don't need a "comprehensive" all-inclusive migration. I care specifically about 2 items: Content and Users. I think I can build everything from there. The users seem pretty straight forward, they are in elgg_users_entity. No problem there.

I have not seen much in the form of scritps to do the migration for content though. Looking at the Elgg tables, I don't see much I can go by. I can see the stories are inserted in the elgg_objects_entity, not sure how the author id is determined.

Any ideas? Anybody has migrated/imported content successfully from Drupal?

Thanks!
