The first one was converting Blojsom to WordPress, but this wasn’t too bad because both work around the RSS 2.0 format. Getting the comments, tags, metadata out and into the rss 2.0 feed was a real pain and I’m convinced I dropped a load of trackbacks and pingbacks in the process. This is another reason why I started using Disqus for all my comments.
The harder task was moving blog entries from WordPress to MoveableType. Yes I expect most of you are wondering why I would move from a far superior system to something which most people left in the dirt ages ago. Well unfortunately we still use MT on the bbc.co.uk/blogs platform and that means as backstage moves to the official blog platform, some mug had to find a way to down convert to MT 4.1 which only imports/exports in this crazy text only format.
So after lots of looking around, I finally found a XSL which I modified to do the job from a stripped down WordPress WXR file (RSS2.0 with lots of WP namespaces stuff). Its important that you strip down the WXR file as it might not be valid XML, so no XSL transform is going to work. I also took a bit of time to write a XSL to remove most of the namespaces elements or convert them into a more valid RSS 2.0 element. You can do the same with lots of finds and replaces, so I won’t post the simple XSL.
Hopefully this will save others a lot of time in the future, if your faced with the same problem.
