Copy feature layer while keeping the objectid

Question

Hi
What is the geoprocessing tool (python arcpy) that will allow you to copy a feature table while keeping the object id?

DaleHoneycutt · Answer

Try using a featureSet load/copy, as in:fs = arcpy.FeatureSet()
fs.load(input_table_path)
fs.save(output_table_path)

I believe the Copy tool will do that for simple features, but you should verify the result.  Complex relationships and feature types (topologies, network datasets, feature linked annotation) won't be ported and may not even work with that tool.

Add a field and calculate it to the object ID
OIDs are dynamic and system generated;
 you cannot rely on them in any way over more than a very short time frame.
