1. Create a feature class (NAME1) from an sde export file by using the command:
sdeimport -o create
2. In ArcCatalog, register NAME1 with the geodatabase.
3. In ArcCatalog, rename NAME1 to NAME2.
4. Add NAME2 as a layer in ArcMap. (Note that the layer still displays as NAME1.)
5. To correct this, change the layer alias to NAME2 to match the feature class.
