For those of you using SharePoint Online on Office 365, you may have heard about the new SharePoint Modern User Interface (SPfx) that Microsoft is slowly rolling out.
Many of us in the SharePoint community are really excited to see the SharePoint look and feel brought up to date with responsive design, and a fresh new experience which aligns better with the rest of Office 365 services. It really is laying the groundwork for a Digital Workplace and an eventual seamless experience between SharePoint and other services like Groups, Planner, OneDrive and more.
However, when is the right time to move to this new Modern UI? When should you open it up to your user community in a production environment? The answer to that is not for a while, perhaps 12 – 18 months. Why? Well because the Modern UI is only about two-thirds of the way there.
If you have existing SharePoint sites, you will find that the Modern UI will only support some of your list types. It only supports custom lists and not Tasks, Calendars, Contacts etc. Those will still display in the Classic UI. So your end-users will see two different UIs depending on the type of list they are in. This will even change where and how navigation is shown. Now that will really mess them up! Feel free to peruse this article which dives deeper into Modern Vs. Classic Interfaces.
