Thanks very much for the helpful info. Generate_key is a great find, and it's useful to know that we should waste out time trying to export key_names at this time.
As for preserving reference links, do we need to create a translation table [entity type, old_key, new_key] and do writes to the table as we upload each entity, and reads to determine new reference value as we upload references? Or is there some, more built-in way to handle this?
