I had no idea it would be so painful to convert my site from Drupal (6.x) to WordPress (3.x). A web search returns many solutions to the problem. The post I finally used was this one from Scott Anderson. It worked ok but it did not bring over any of my attached images and I had to assign categories and add some menu and page items.
I was grateful for what it did do (including dates, posts, and tags) and luckily I haven’t written many posts so it was not too bad. But if you had 100’s of posts I think I would choose a service like: gConverter – for $75 it is hard to beat.
