I have noticed now, that since recreating the entities, using a new parent 
(as outlined above), that there are now occasional ID allocation issues ( 
BadRequestError: 
the id allocated for a new entity was already in use, please try again )

I find this strange as I would expect Id and parent key to form the key and 
wouldn't expect there to be conflict.

Why does changing the parent key potentially causes id allocation issues 
when new entities are created? Short of deleting old entities, what's 
another approach for this situation (where id allocation is failing).

Thanks
Rob
