migrating mails between two cyrus servers keeping seen states

[Marcus Schopen via Info-cyrus]

Hi,

I'm planning to move some mailboxes from a cyrus server (2.1.18 - which
is a kind of mail archive) to another one (2.4.17+caldav~beta9-3).
Playing around on a test system with copying a user's mailbox and doing
a following "reconstruct -r" came out with a mailbox without seen states
on read mails on the new system; all mails unread. Normally I move
mailboxes using imapsync to keep states etc., but on a number of really
large mailboxes the initial sync takes days. Any other suggestions than
(slow) imapsync tools?

Ciao!
Marcus

Befor 2.4.x the seen information was stored in extra files in /var/imap/user
Did you copy these files too?

Ah, it's an old Debian system. These files are stored in
eg. /var/lib/cyrus/user/t/testuser.seen. Where do I have to copy this
file on the new server to? And there is a testuser.sub in the same dir,
which contains the subfolders. What about this file?

Ciao!

The seen information is now included in the cyrus.* files (i think in  
the index file),
but upgrading form an older version with reconstruct should check the  
.seen file at
the old location. The location depends on your setting of  
configdirectory, fulldirhash

and hashimapspool in impad.conf.

The handling of the sub file has not changed. But you should copy them  
to the new server,

if you want to keep the subscription information.


You should check
