November 2019 Release Notes



  • New app-based authentication launched 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.

This app must be added in both tenants (Source and Destination) to reduce throttling and failures due to Microsoft throttling policy changes. Refer to this help article for more details. 


  • Advanced Options
    • Set a limit of 400 for the 'Maximum number of concurrent migrations' to better manage the processing capacity. 
    • After the fix, the user will see a warning if the number exceeds the 400 limit.


  • Teams to Teams Migrations 
    • Improved error messages when an Assessment fails.
      • Previously, the error message did not indicate which specific user e-mail address was not a Global Administrator.
        After the fix, the specific user e-mail address is clearly indicated.
