For the record, I did not find migrating my code from using Blobstore to use 
GCS easy. It took me a significant effort to understand what works and what 
does not and then rewrite the appropriate parts. Hopefully some of the issues I 
faced are now mitigated but not all of them, after all you have to change code 
that works and maybe you do not even understand any more.

Read this SO thread for some of the gotchas:

http://stackoverflow.com/questions/19287709/blobinfo-object-from-a-blobkey-created-using-blobstore-create-gs-key

Currently all my new uploaded images end up in GCS but I still left the old 
ones in blobstore to avoid the day zero migration headache. Maybe one day I 
will be forced to move those over as well, this part should not be too much 
effort.

Since blobstore file api was deprecated for a short while, I'm thinking if I 
should migrate those api to cloud storage or still use blobstore api to store a 
bunch of images. Also since cloud storage is not free, I might prefer to use 
blobstore as long as it won't be deprecated in the near future. Any suggestions?


Go ahead and use blobstore for now if the cost issue is big enough, otherwise 
use Cloud Storage. While there have been rumblings that blobstore will 
eventually be deprecated, it's easy enough to migrate to Cloud Storage when 
that occurs.
