Appending Data to Geodatabase that is not in the same coordinate system

GISUSER6

If I wanted to append a shapefile that is in WGS 1984 to an empty feature class within a geodatabase that is in a local county coordinate system (NAD 1983 HARN etc.), would I need to project the data before appending it? Or does a transformation occur within this tool somehow? I did not see any transformation in the python scripting of the tool when I ran a test without projecting any data.

Thanks!

The input and target datasets may have different spatial references. When this is the case, the tool projects the input features to the target's coordinate system. For best results, specify an appropriate geographic transformation using the Geographic Transformations environment. If the target dataset is a map layer, the tool may apply a default transformation. In Python, there is no default transformation.

Are you using the "Append" tool?

Is the "geodatabase" file geodatabase or enterprise (and if so, which RDBMS)?

Even if it would allow it, I wouldn't be terribly comfortable trying to project on the fly as an append.

Yes, I am using the append tool and it is a file geodatabase .
