The seen information is now included in the cyrus.* files (i think in  
the index file),
but upgrading form an older version with reconstruct should check the  
.seen file at
the old location. The location depends on your setting of  
configdirectory, fulldirhash
and hashimapspool in impad.conf.

The handling of the sub file has not changed. But you should copy them  
to the new server,
if you want to keep the subscription information.
