.NET Agent >= 20.3 supports .NET Core. If you used the Microservice Agent to monitor .NET Core applications you can monitor .NET Core with the full .NET Agent. You may receive an error message in the MSI Installer stating that another version of Splunk AppDynamics is detected.

The Microservice Agent uses a JSON file to store configuration information while the .NET Agent uses an XML file. The data does not migrate between these files.

To fix this issue, you need to map the data in the JSON file to the XML file, config.xml and remove environment variables. If you have completed the instructions above and still see the error, you may need to reboot your machine. You may want to plan reboots according to your planned outage schedule.
