We know what you’re thinking: Financial Services Cloud is already available in Lightning Experience. You’re right about that. Although we optimized Financial Services Cloud for Lightning, the app was built in Salesforce Classic. We think it’s worth your while to upgrade. But don’t worry; the Financial Services Cloud app isn’t going anywhere. It remains available to retain your customizations. With a simple post-upgrade step, you can port over your customizations to the Wealth Management app and enable your Financial Services Cloud (Classic) app to be visible only in Classic.
