Maildir is better for performance.

- how to migrate user password from /etc/shadow to mysql?

If your passwords are encrypted in MD5, Try to copy them into mysql directly.

even when i store maildir on nfs ?

What about migration mails stored by uw-imap (webmail) - there in possible to migrate it on-line - i must reduce downtime.
I decided to leave old server with old mails for 1 month after migration (access thru old-pop3 and old-webmail).

For some people i must migrate maile from old to new server - how can i do that ?
