Actually there is a problem is you store content keys as string in the datastore. They can't be imported back in another application because keys are "application prefixed". I was hit by this problem and I'm still stuck to my old application that I can't rename.
I think GAE really miss an easy to use backup/restore tool. I know that it's probably quite complex to implement though.
