Hi,
This is my system configuration:
- Water Utility Network version 6
- ArcGIS Enterprise 11.1
- ArcGIS Pro 3.2.2
When I start the tool "Reconcile Version" with post and delete, I received this warning/error.
This error ocurrs in some versions, not all. Some versions we can reconcile and post with sucess.

Recently we updated the enviroment to 11.1, before was 10.9.1, and, we updated utility network version too, for UN 6. Before the updated, we never received this error.

The Default version is set to protected, but, before was set too.
