Hi everyone.

Totally new in the world of cyrusimapd, I'm trying to migrate my current
imap server from dovecot to cyrusimapd.

I'm still in the prototype stage.

I've ~ 4To of mailbox for ~ 2000 users.

I would like to know what's the best way to migrate all mailbox and

I already try imapsync, but how can I do that without knowing the password
of my user ? I think they are something call master user in dovecot, but is
they are anything similar in cyrusimapd ? And if yes how I choose the user
name in imapsync ?
