Will Not Be Addressed
The development team has considered the issue or request and concluded it will not be addressed. The issue's Additional Information section may contain further explanation.
The issue here is that this data is not valid for the geography spatial type. There are slivers that exist which overlaps when stored in the geography type because of the curvature that exists with the geodetic model. The geometry storage which uses the planar model does not cause the overlapping with a flat earth model.
Use ArcGIS Desktop 10.2.1 to load geography data into the ArcGIS Desktop 10.2.1 enterprise geodatabase.
