Migrate QMail to Cyrus

Read this link, and then you know why mailutil is NOT good enough.


I am also having this problem.
To improve the speed, I have to tar the mail to the new server and do 
reconstruct, and then use imapsync to re-build the imap flag and re-subscrib 
the imap folder.
However, I am still not satisfied by this method.

Please kindly share me a better way.

BTW, people using SAN for clustering solution is welcome, too.
