We are D365 on-premise all are users use legacy/classic interface. We are now planning to shift users to the new UI.
When I check system settings I see below, does that means once UI is enabled, I will have no access to legacy/classic interface?
How do I get a copy of the existing classic url in UI app? Should i have a separate app for users or same app but obviously they will still continue to see based on security roles.
Do i also need to say Yes for Show legacy D365-custom app option? what does the recommended part under this means?
Thanks
