As of July 16th, 2009, 80% of all activities have been migrated from Motionbased to Garmin Connect, with the remaining 20% to be completed over the next several months. For more information on the migration process, please see this announcement:

In case no-one knows, that URL is broken. Well, it is at the moment.
I'm also slightly worried that having trusted MotionBased to store all my data, and once in there, having no real way to download it all it may be lost. I had a paid subscription to MotionBased but doubt that matters.
Old information is very useful as for example, I was in an enduro race yesterday and want to compare part of the performance with how I went last year. Sadly as the old activity seems to be awaiting migration this is impossible. I can't even dot race the two on MotionBased as the old activity isn't available there for some reason (and can't upload the new anyhow).
I'm also slightly worried about the point raised here:

Once registered on GC I connected my device and told it to upload new. There were loads of duplicate activities like this that appeared. I would hope that data from Motionbased will be deemed more complete than these 'summary' activities that the GC plugin created from the device history.
If we could we please have an update on this that would be very useful.
Thanks
