But it will require a little extra brain power and geek savvy to pull it off. Google has just released a new application to convert blogs from one platform to another without content getting lost in the translation.
It happens. People get fed up with their blogging platform from time to time and then what? Google Blog Converter is an open source app that accomodates all the major blogging tools (Blogger, Moveable Type, Typepad, WordPress and LiveJournal). So, you can convert among them with relative ease.
The application is written in Apache (that's an open source code). I would make sure you read the "read me" and make sure you have the tech chops to pull it off.
