It was mostly just a find-and-replace session when I did it four?
years ago.   I converted everything, though -- I didn't convert only
the EOF part.

For the EOF part, it was an easy transition.   Load the model into the
Cayenne model and save it out again.  For java, change the class and
method names names and delete the .lock() statements :-)

The biggest pain was switching between NSDictionary and Map:  the
arguments are reversed for the put()  method.
