You shouldn’t notice any major changes on the front end other than a few minor enhancements, but I’ve switched over from Drupal 6.9 to WordPress 2.9. When I first moved to Drupal from Coranto a little over one year ago I quickly mashed together a template. This move has allowed me to completely re-write the site to make it cleaner overall.
The major things that you should know is that my rss feed has moved from /rss.xml to /feed. The old link will still work, but I recommend you update it just in case. A few old links may be missing here and there, but all posts, pages, and comments have been moved over from Drupal. If you encounter any other weird issues, please leave a comment.
