I'm testing my new hrd version of the app now. I have found some differences that need to be debugged. One thing I wish I had done before migrating (not mentioned in docs): upgraded my appengine SDK to the latest version before starting the migration...

My sdk is: release: "1.5.2" On Tuesday, January 15, 2013 7:44:15 AM UTC+8, Takashi Matsuo (Google) wrote: > > > Hi Dennis, > > On Mon, Jan 14, 2013 at 11:00 AM, Dennis <denni...@gmail.com <javascript:> > > wrote: > >> oh, now i see the instructions: they are not in the docs but only appear >> on the migration webpage when the migration reaches the last phase: >> >> >> The data copy is now complete.
