Copying Blobs from one AppEngine application to another

Question

I used the functionality provided by Google App Engine to copy all data from one application to another. What wasn't transfered though were my Blobs. How can I make a copy of it to my new application?

Answer 1

Blobs can be served. This means they can be fetched by your other application. See my answer to this question a couple of days ago: How to fetch image and save to blobstore?
