Has anyone attempted a migration of existing multiple blogger content from Plone to WPMU? Plone was a feasible solution for us, when we started out; but, we've pushed it beyond its original intent and I've recommended WPMU. Of course, that also means migrating all the existing content. I'm anticipating downloading data into .csv, converting to xml, running field matches, batch upload to my WPMU db. However, I'm not a Plone wizard. Anyone out there have a clue about this?
