Salesforce Lightning Experience version upgrade to Content Organizer is now for general release. This version takes advantage of the Salesforce Lightning Experience user interface, but don’t worry the classic version is still included.
We recommend that you install the application in a sandbox and ensure it meets your needs as the Lightning Experience version does not have all of the same functionality yet as classic.
