MigrationWiz New Feature: SharePoint App-Based Authentication
Last month, we launched new app-based authentication for SharePoint, OneDrive for Business, Office 365 Groups (Documents) migrations, and Teams migrations. This app will provide greater security and reduce the potential of Microsoft throttling. It will replace the previous Office 365 authentication, which has been subject to increased throttling by Microsoft recently. This new authentication method is specific to Office 365 tenants.
Note: This app must be added in both .microsoftonline.com tenants (Source and Destination) to reduce throttling and failures due to Microsoft throttling policy changes. Refer to this help article for more details.
