I am experiencing problems when exporting a file geodatabase feature class to shapefile. The file geodatabase feature class has more than 6 million features and 19 fields. In ArcGIS Pro, I exported the feature class by using the Feature Class to Feature Class tool. While the geometries were exported correctly, the attributes in the shapefile are mixed up. For example, a feature that is located in country A got the attributes of a feature located in country B and vice versa. I also tried exporting the feature class with ArcCatalog, but I am facing the them problem there. Any idea about the cause of the problem and what I can do for a successful and correct export? I am using ArcGI Pro 2.4.3. and ArcGIS Desktop 10.7.1.
P.S. I need to export to shapefile since I need to share the data with a colleague in another organization who can only read shapefiles.
