Hi, I don't know what silly things I did or failed to do before. After reading your replies, I rsynced just my inbox and my seen and sub databases again and it works. This time because I rsync small amount of data, I stopped the cyrus service on the production server which I didn't do before. So I will do a mock migration and ask people to check. Then I will do the live upgrade. Thanks for your expert advice.
