A shot in the dark, because I am not sure what you mean by "a dead zope 

Create an external method that you can access from the 'non-dead zope 
instance', which directly accesses the Data.fs file from the "dead zope 
instance" (using the usual db.open/root=connection.root...) and then loops 
thru all of the objects from the root down and copies them into the 'live' 
zope instance.
