Okay I came across this in CIT, where someone wrote to MSN asking them why we can't Migrate existing Groups to MSN Live Groups; here is his e-mail and their reply!
"I appreciate that for whatever reason MSN Groups is no longer considered Manageable but as it is being superseded why can't existing Groups Data just be moved over.

"Hello Rxx,
Thank you for writing to MSN Groups Technical Support. My name is Nadia and I understand that you want to know why it is not possible to migrate your site to Windows Live Groups. I realize the importance of addressing this matter.
Rxx, we plan to launch Windows Live Groups to the public in the coming weeks, as a service that helps small groups or clubs collaborate online. Because this first version of Windows Live Groups is a good fit for smaller groups we chose Multiply for moving small, medium and large Groups to a new service now.
We appreciate your continued support as we strive to provide you with the highest quality service available. Thank you for using MSN Groups.
Sincerely,
Nadia
