After trying around for some time I think I found out why it didn't work for me: I had no direct references to Blobs in the Datastore. I was only storing the keyString of the BlobKey, not the BlobKey itself (mainly because I'm using the entities in GWT).
After updating my entities to hold the BlobKey instance rather than a String, the Blobs where successfully migrated. Maybe that'll help someone else... It would be nice to add this requirement to the migrations docs.
The checkbox to "Migrate Blobstore Data" seems to just not exist anymore, but it works. It would also be nice to remove that from the docs to avoid confusion.
Cheers, Thomas.

i have the same issue, blobs are not showing up.. I'm also not seeing the "checkbox labeled Migrate Blobstore Data" as described in the documentation. I've upgraded both apps to GAE SDK 1.7.2
