Turn On Lightning Experience (Critical Update)

Salesforce will turn on Lightning Experience starting within 72 hours of January 7, 2020 to empower users to move faster, do more, and be more productive. We encourage everyone to start preparing to transition to Lightning Experience soon so that your users can benefit from everything the new interface has to offer. The future of the Salesforce user experience and platform is Salesforce Lightning. Moving forward, all innovations will be in Lightning Experience. Take advantage of the lead time before Lightning Experience is turned on to understand how your org’s features and customizations perform in the new interface and to prepare your users via change management. Start now to ensure a better experience for everyone when Lightning Experience is turned on later. Better yet, take control and turn on Lightning Experience for your users before this update is auto-activated, on your terms.

Where: This change applies to Group, Developer, Professional, Enterprise, Performance, and Unlimited editions for orgs that don’t yet have Lightning Experience turned on yet.

When: This update starts appearing under Critical Updates on January 28, 2019. The update begins auto-activating within 72 hours of January 7, 2020.

Who: All users with the Lightning Experience User permission enabled are affected by this critical update. This includes all users with standard profiles and users with custom profiles or permission sets that have the Lightning Experience User permission enabled by an admin. In Salesforce Classic, users see two options to switch to Lightning Experience: a link to switch to Lightning Experience appears in the header and in the user profile menu.

To encourage everyone to work in Lightning Experience, users working in Salesforce Classic are switched to Lightning Experience on a weekly basis. Users can switch between Salesforce Classic and Lightning Experience from the user profile menu.
