A SharePoint communication site is a great tool for sharing information with others in your organization. Now, classic team sites can enjoy the benefits of modern communication sites.
This is an optional feature that will not have any impact in your environment until a SharePoint admin or site owner enables this feature on a site.
To enable this feature on a classic team site, a SharePoint admin or site owner must run a PowerShell cmdlet. Enabling the communication site experience does not change any site permissions or remove any content. Learn how to run the PowerShell cmdlet.
