If it's an SDE Geodatabase you can usually read directly from the underlying database (e.g. Oracle or SQL Server) using the relevant reader in FME.

However:

  • It may be difficult or tricky reading the geometries (hint: cast to WKB in a SELECT statement, if possible, then use the GeometryReplacer in FME to restore the geometry)
  • It may be difficult or complicated getting to SDE specific functionality, such as topology definitions, relationships, domains, etc.

This blog hints on how to get to the Utility Network Data element using REST API and JSON parsing.

https://www.esri.com/arcgis-blog/products/utility-network/data-management/exporting-subnetworks-using-data-interoperability/

If you take the SDE approach, then the GDB items table should be your start and this would require XML parsing. Blog supports UNv3 and I'll update into UNv5 and add a sidebar on how to get other UN and GDB properties like Attribute Rules.
