When copying feature classes from an OGC‑compliant GeoPackage (gpkg) into a File Geodatabase (gdb), attribute domains defined in the GeoPackage are not transferred. As a result, users must manually extract these domain definitions using an arcpy script with SQL queries, import extracted domains into the File Geodatabase, and then reassign them to the appropriate fields.
This adds unnecessary complexity to workflows that involve standardized data exchange, particularly when GeoPackage is used as an interoperability format or standardized exchange format.
Proposed Enhancement:
Enable ArcGIS Pro to automatically transfer attribute domains from GeoPackage feature classes/layers into the File Geodatabase during the copy/paste or export/import process and assign them to correct attributes.
