I don't think any code exists for that. Following the guidance in this page I guess it had to be written for each new case.

reading, again, the http://docs.ofbiz.org/display/OFBTECH/General+Entity+Overview it struck me that adding in a method that looks for the old_ entity a database could be converted or upgraded. by this I mean actually move data, if so required. This would require a sub element to the field that point to the new field, in the old_ entity. Forgive me if this is already done, I did not find in my search.
