Where: This change applies to Lightning Experience and Salesforce Classic in Enterprise, Professional, Performance, Unlimited, and Developer editions.
How: The Configuration Converter is a standalone tool that lives outside of Salesforce. We recommend that you run it in a sandbox or Developer org first and then migrate your changes to your production org. To get started, visit https://lightning-configuration.salesforce.com/ and log in with your org credentials.
