OK, thanks for the good information.  I was using tar and scp to copy the
/var/spool/imap/letter/user/username and
/var/lib/imap/user/letter/username.seen from the old server to the new.

I shutdown cyrus-imapd on the new server and used rsync -av to copy both
the above and started cyrus-imapd and there were no messages regarding
reconstruction of seen and the information was preserved.  The messages
now appear with the correct seen state.

thanks much for everyone's help! S
