Indexes are not part of datastore and are not migrated, they are defined in your app and built after being uploaded as part of a deploy or index update via appcfg.
Existing entities (by key match) are overwritten. "Extra" entities you had at destination before copy are not deleted. Mine worked fine and keys maintained. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
