MT2SP Blog Migrator
This tool will migrate a movable type blog to a sharepoint blog. Support is included for transforming post data (media links) to a new location (i.e. sharepoint list)
note that this is a tool written specifically for the purpose, it’s not pretty and could do a lot more, however, it’s done the job and the task is now complete. As far as my support goes, it’s unlikely it’ll see many updates now as I have no need to further it myself. It could automatically create the categories by pulling the out of the export then creating them on the fly, it could also clear down the lists before it posted to them, or even post the images to lists. All of this is possible via the lists web service which i’ve used to post the content. You’ll need to mess around with some CAML but adjusting the code should be very easy after a bit of googling.
