shared folder seen db

[Francesc Guasch]

Hi. I migrated a old cyrus-2.1 to a new server with cyrus-2.2.

The seen flags from the INBOX and user subfolders seem fine but
all the messages from the shared folders are unseen.

I searched the archives but I am only able to find about "sharing
the seen flags in shared folders".

Where are the old server 2.1 seen databases for shared folders ?
How can I dump it to cyrus-2.2 ?
It looks like they are not in /var/lib/cyrus/user/username.seen.

Any hints ? thank you very much.
