Migration Problems UW -> Cyrus: Preserving Mail Flags

[Axel Wagner]

Hi,

RE: forget the banner...

I am currently in the process of migrating approx. 100 GByte of mail from UW IMAP to Cyrus IMAP.

Using the filesystem copy and "reconstruct -r" approach
mentioned on the Wiki, I have encountered some strange behavior.

When I use imtest(1) to connect to some user mailbox as admin user cyrus, I don't see any mail
flags. And in my case, even worse, I cannot set e.g. the \Seen or \Answered flag.

But when I connect as a regular user and select a mailbox using the "INBOX." notation, I see all
the flags and can also modify them:

How come?

Without being able to set user flags as administrator, our migration process will not succeed
(user will complain having thousands of NEW emails...)

Looking forward to your help...

Thanks!
