The Lightning Experience Configuration Converter has been expanded to address even more configuration issues for the transition to Lightning Experience. 

• AppExchange Packages: Now you can evaluate your org’s AppExchange packages for Lightning Experience. The new AppExchange Packages tab provides a real-time assessment of how ready existing packages are for the new interface. You can see if each installed package is ready as it is or if it needs to be upgraded to a Lightning-ready version.

• Hard-Coded URLs:  Hard-coded URLs aren’t supported in Lightning Experience. With the new Hard-Coded URLs tab, you get a real-time assessment of existing hard-coded URLs and can automatically convert them to My Domain URLs with a click. You can convert select URLs or mass-convert all of them at once. 

Note: The AppExchange Packages and Hard-Coded URLs tabs are currently available in Beta. We recommend running these tabs in a Sandbox org first. 

These tabs replace the AppExchange and hard-coded URL sections in the Lightning Experience Readiness Report. These sections will be removed from the Readiness Report in the near future.

For full details about the new tabs, check out “Review AppExchange Packages for Lightning Experience Compatibility (Beta)” (https://sfdc.co/clBAmI) and “Update Hard-Coded URLs for Lightning Experience (Beta)” (https://sfdc.co/4GRQm) in the Salesforce Summer ‘19 Release Notes.
