I'm planning a migration from Cyrus 2.1.9 to Cyrus 2.2.12 (Suse->Gentoo)
but i have few doubts.
Unfortunatly clients are Outlook with POP3 "leave mail on server" (they
cannot use imap for several reasons)
I know how to keep mailbox structure (as they also access mailboxes
through webmail and take benefits from imap features)
My problem are UIDLs.
If those uidls change...all mails are re-downloaded (we're talking about
gigs mailboxes)
I think they are stored in cyrus.* files.
The Cyrus POP3 UIDL format is "<uidvalidity>.<uid>", where <uidvalidity>
is the IMAP UIDVALIDITY of the mailbox (stored in cyrus.index) and <uid>
is the UID of the message (same number as the message filename).
So i shouldn't have problems migrating.
But i would like to be sure that file formats are compatible and a
reconstruct won't change them.
Reconstruct *will* change the UIDVALIDITY, therefore the UIDL will change.
The Cyrus 2.2.12 code *should* upgrade the mailboxes on the fly without
changing the UIDVALIDITY.
