Hi, I am building a web app using GAE Java. I have a class that uses a Long ID as its primary key.
I now want to create a new class that would be the parent class to this original class (a one to many relationship) however the children that already exist need to have a primary key of type "key", not the Long ID I have now. What is the best way to change the primary key to be type "key" instead of long for the existing persisted entities? Should I create a new class with primary key of type "key" and instantiate and persist new objects that copy the field values from the old ones? Or can I somehow just update the existing class?
