How can the system manager enable edit capabilities after publishing a test service where only the Feature Access capability is available?

To enable edit capabilities on a test service that currently only allows the Feature Access capability, upgrading the ArcGIS GIS Server license level is the appropriate action. The licensing of ArcGIS GIS Server determines the capabilities available, including editing features within services. If the server is currently licensed only for a level that supports limited operations and does not include editing, upgrading allows for extended functionalities.

This action directly influences the operational capabilities of the services published; therefore, once the license is upgraded, the service can be configured to support editing operations. In environments with different levels of licensing, it's essential to ensure that the right level is in place to access desired features such as editing.

Modifying feature service settings in the portal does not affect the underlying licensing restrictions; it only allows for the adjustment of parameters within the existing configuration. Reinstalling the software would not inherently change the licensing options available either. Changing the service type to Feature Service does not address the fundamental limitation imposed by the licensing level, as simply designating a service as a feature service without the correct license will not enable edit capabilities.
