App Engine . , , , . Java-.

If your organization has already been deployed to production and you delete the field, this will not retroactively remove the property from objects that have already been saved. You will need to create a task queue task set to go through and re-save all of these objects. It is probably best to take this step before moving to a new facility so that you don't break your business logic elsewhere.
