The SharePoint Migration Tool lets you migrate lists or files from your SharePoint on-premises document libraries or from your on-premises file shares and easily move them to either SharePoint, OneDrive or Microsoft Teams in Office 365. It is available to Office 365 users.
Designed to be used for migrations ranging from the smallest set of files to a large scale enterprise migration, the SharePoint Migration Tool will let you bring your information to the cloud and take advantage of the latest collaboration, intelligence, and security solutions with Office 365.
Microsoft Teams and SharePoint File Storage
With Microsoft Teams you can create a more open, digital environment. Microsoft Teams is a chat-based workspace that brings together people, conversations, content and tools—creating a more open, digital environment. Threaded conversations make it easy to understand what each employee is referencing, and employees can co-author and collaborate on Word, Excel, PowerPoint, and OneNote documents without ever leaving the app.
Both Teams and SharePoint team sites are organized by topic, project, organization, or some other focal point for a team of people. Hence, in any given organization, Teams and channels will often follow a similar structure to SharePoint team and project sites.
