[Frank Patzig]

Hello,

i will migration a 4TB mailsystem.

I have with seen migration a problem. I sync the
/var/lib/user/[a-z]/uid.seen from old system. The owner and groups are
correct. The db is skiplist.
I start reconstruct -rf , then start the cyrus deamon.

In the mailclient are the mails unseen. The data migration from *.seen
to cyrus.index not work. What can i do? In strace not found not data und
in the logging not importent informations.
