We're helping out a new client with a site that's currently on ModX and was abandoned by the original developers... We're migrating it to Drupal 7 to take advantage of Solr and a bunch of other stuff, and I'm wondering if anyone else has any direct experience with moving from ModX to Drupal?

Currently planning on using some custom CSV exports out of their MySQL db and importing them using Migrate. Anyone know of any pitfalls to watch out for? Roadblocks, etc?

Thanks much!
