If both servers are using IMAP, maybe imapsync
(http://imapsync.lamiral.info) would be an easier way to go...

Hi there,
I have to migrate data out of a very old (debian 4) and buggy cyrus
mailserver.
About 40 Users with 200000 Messages each.
Doveadm backup works quite well and gives me most of the mails. About
every 100.000 Mail
cannot be exported by cyrus. I do not want to bother about these errors.
Maybe it is filesystem, maybe it is memory leak, or cyrus bug or whatever.
My problem is that doveadm backup exits with an error if it cannot
read a mail.
Is there some way or option to make doveadm backup just skip the
errors and continue with the next message ?
I want to use doveadm sync because it preserves the uids of the mails.
Imapsync works great but does not prserve uids.
cyrus2dovecot is not an option because it does not work incremental
and conversion would take far too long.
Any ideas what I can do ?
Thanks
Christoph
