What about solving db-update through a porting utility?

We will need 2 database schemas (the old and the new one), but since we 
will have to develop a porting utility all the same it would be easier 
to just add (eg) a new "menda 1.x" possible porting source to it than to 
develop a whole new tool.

Besides, does anyone know if it is possible to have two hibernates 
running with two mappings for the same classes and connecting to two 
different databases?

If this is possible, writing a porting-client would maybe be a matter of 
reading the whole old database into objects, manipulating them (eg. to 
fill fields required by menda but not by the old source) and marshalling 
them to the new one...
