Upgrading the DNS Integrity Gateway will preserve any custom settings in the permissions.json file in the <dns_integrity_gateway> directory. Custom settings in the config.py file in the <dns_integrity_gateway> directory will also be preserved. Refer to the DNS Integrity Gateway Release Notes for details on any modifications to the available options within the config.py file.
Attention: You must install Docker and the Python Docker SDK before installing DNS Integrity Gateway. Docker installation is only necessary to run the Gateway application.
