How to Handle ApplicationImpersonation Retirement in BitTitan MigrationWiz
Question details
Users migrating from Google Drive to OneDrive using BitTitan MigrationWiz need a workaround for Microsoft's retirement of the Exchange Online ApplicationImpersonation role.
- Product
- BitTitan MigrationWiz
- Device & OS
- not provided
- Scenario
- Executing a Google Drive to OneDrive migration when BitTitan MigrationWiz requests the deprecated ApplicationImpersonation role.
- Observed behavior
- Microsoft is retiring the ApplicationImpersonation role for new assignments, blocking traditional migration authentication methods and requiring a shift to OAuth.
Ensure you have global administrator access to your Microsoft 365 tenant so you can grant the necessary OAuth permissions for the migration.
Configure MigrationWiz with Modern OAuth Authentication
Transition your migration endpoints from ApplicationImpersonation to modern OAuth authentication via the Microsoft identity platform to ensure continued support and security.
Microsoft is deprecating the ApplicationImpersonation role to improve security across Exchange Online environments. While existing role assignments might function temporarily for ongoing tasks, all new migrations must utilize OAuth.
BitTitan MigrationWiz fully supports modern authentication, meaning you can bypass the retirement warning simply by updating your endpoint configurations to use Microsoft's identity platform.
Check your Microsoft 365 Exchange admin center. If you have an existing ApplicationImpersonation assignment, you may finish immediate tasks, but do not rely on it for new migration projects.
In your BitTitan MigrationWiz project, edit the destination endpoint settings. Remove legacy credentials and configure the endpoint to use modern OAuth integrated with the Microsoft identity platform.
Navigate to the BitTitan Help Center and follow the specific 'Google Drive to OneDrive for Business Migration Guide' to properly authorize the MigrationWiz application in your Microsoft tenant.
Ensure Smooth Document Access After Migration with WPS Office
Backend migrations can be highly complex and disruptive. Guarantee that your team has immediate, reliable access to their documents during and after the transition from Google Workspace to Microsoft 365 with WPS Office—a lightweight and highly compatible suite.
- 1. Download the software: Visit the official WPS Office website and download the free installer for your operating system.
- 2. Install the suite: Run the setup file and follow the quick on-screen instructions to deploy WPS Office on your machine.
- 3. Open migrated files: Launch WPS Office and instantly open your newly migrated OneDrive documents with perfect formatting preservation.
Frequently Asked Questions
Why is Microsoft retiring the ApplicationImpersonation role?
Microsoft is retiring ApplicationImpersonation to enhance tenant security. They are replacing legacy RBAC roles with modern, more secure OAuth authentication and scoped permissions via the Microsoft identity platform.
Will my current MigrationWiz project break immediately?
Existing ApplicationImpersonation assignments may continue to work temporarily to allow ongoing migrations to complete. However, no new assignments can be made, and it is highly recommended to migrate to OAuth as soon as possible.
Where can I find the specific OAuth setup steps for BitTitan?
The step-by-step OAuth configuration instructions are located in the BitTitan Help Center under the 'Google Drive to OneDrive for Business Migration Guide'. This guide is updated regularly to reflect Microsoft's current authentication requirements.
