The Public Sites Content Migration app will copy content (pages, images, documents, etc.) to the new Office 365 public site, minimizing the need for time-consuming manual work.
The Public Sites Content Migration app will also perform automatic configuration of common site settings on new public site, such as setting the site title, creating pages, configuring navigation, and setting the footer.
The app is intended to support basic scenarios. Additional manual work is expected for customers with complex and heavily customized sites.
