You can simply add the new property, and then either write a simple builder to visit all the cases when this class was subclassed or used as a member somewhere, or add some code to the class to check whether new is not changed but old is, then copy value from old (maybe a new_property_access?). Or do the 2nd to hold the fort until you're done with 1st.
