claireking.ck-conception.com is the address of the development site - it was set up to forward to the live site on going live so that any beta testers who forgot to update links would be sent to the live site. There was only a week of beta on claireking.ck-conception.com so I'm not worried about keeping those stats/subscriptions.
The only real problem is that I re-set-up Jetpack on the test site *before* the migration (using my usual wordpress id) so after the migration, wordpress.com seems to see it as a seperate entity even though the domain name and wordpress.com ID are identical.
In wordpress.com (linked from my site admin jetpack admin page) I see http://www.claire-king.com listed twice in the dropdown - I'm guessing one is the old site, and the other the new.
What I'd like, please, is to merge those two instances of http://www.claire-king.com stats and subscribers into a single http://www.claire-king.com database.
If that's not possible, my next best option would be to lose the new http://www.claire-king.com stats/subscribers and to restore the old stats/subscribers as the sole database associated with http://www.claire-king.com
Many thanks for your help!
