No, we moved off from the script as it was incredibly slow in processing a forum with 10 million + replies.
We created everything from scratch in C#. Took around 4-5 hours to migrate everthing beside avatars and create redirect to match the different URL formats. A second pass of the script with a specific parameter would also update the avatar for each active users in the last 6 months and add all the necessary redirects by scanning the replies and looking for the old URL format.
That took more or less a couple days but it was something that could happen in the background as the important thing for us was to have the forum up and running with all content in less than a day.
