GConverter recently converted a Drupal 7 site to WP 3.5 for me and it went far better than expected. I'd especially like to thank Paul Davies for his patience.

If you are planning to have this conversion done, I would say go ahead and don't worry. Any probs (and there are bound to be a few with this kind of technical project) Paul and his team fixed things very quickly.

I would recomend if you plan to have thumbnails on your site that you take advantage of their 'Featured Image Service. I didn't think I needed it, but my theme made me realise I did. Faced with manually adding a featured image post to thousands of posts I decided to bite the bullet and get the guys at GConvert to write a script to do it. I'm very pleased with the results, it saved me hours - probably days - of work. Wish I'd chose it from the start though as it's cheaper then.

So my ecperience with GConvert has been very positive, and I'll certainly recommend them to others.

I'm thrilled with the results, so thanks guys! :)
