Set up the app-based authentication in the Office 365 tenant. BitTitan uses app-based authentication for SharePoint, OneDrive for Business, Office 365 Groups (Documents) migrations, and Teams migrations. This provides greater security and reduces the potential of Microsoft throttling. It replaces the previous Office 365 authentication, which has been subject to increased throttling by Microsoft. This app-based authentication method is specific for Office 365 tenants.
Important: This app must be added in both .microsoftonline.com tenants (Source and Destination) to reduce the throttling and failures due to Microsoft throttling policy changes.
If this app is not added on both tenants, MigrationWiz will attempt to create a temporary substitute app in the tenants to be used for authentication. We do not recommend relying on this substitute app creation, as this behavior will only be a temporary transitional behavior within MigrationWiz. To avoid potential interruptions or failures in migrations, it is strongly recommended to set the app up in the tenants.
Add the App to the tenant
Visit the following URL and sign in as the administrator user:
For SharePoint or OneDrive migrations: https://login.microsoftonline.com/common/adminconsent?client_id=e7c20566-14a7-4722-acd1-396f7268ea1a&state=12345
Do this for both Source and Destination tenants.
Authorize the App for both Source and Destination tenants.
