Oh, if you've already moved the mailbox and the seen file hasn't
been moved yet... yeah, that's messy :(

The main problem is that the seen file is indexed by UNIQUEID
rather than mailbox name, otherwise you could just copy-paste
the sequence out and run

TAG UID STORE <paste> +Flags \Seen

via IMAP after selecting each folder.

But I suspect you have hundreds of these folders?  You can get
the UNIQUEID from the cyrus.header file to script it.  You can
use cyr_dbtool from the new cyrus to dump the file and then
use perl or something to munge the data.  NOTE: you need to be
able to log in to imap as the user themselves, otherwise you'll
be setting the wrong seen flags.

Possible cheap-n-nasty workaround is to use an admin connection
and switch each mailbox to sharedseen, apply the flags, then
switch it back.
