That happened to me before when I migrated to HRD. I had my keys stored as strings in the datastore, when I migrated, those stringed keys where not re-written. It was quite a nightmare.

Anyway, your blobstore keys were probably not re-written to point to the new keys in your new app in HRD. It could be because you stored them as a string or something other than the equivalent of BlobstoreKey in Java.
