I believe that GAE does not guarantee that the format of local development datastore "local_db.bin" files remains unchanged between SDK versions. So updating to a newer version of the SDK has the risk that data stored in a local copy of the development datastore is lost.
I remember that there have been previous posts about this issue which should confirm more authoritatively what I mention above. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
