We updated the analysis rules of your source lists and libraries in the app so that larger lists and libraries will migrate faster.

You'll notice better handling of throttling issues associated to 503 errors in Microsoft 365.

We updated how the GUIDs (globally unique identifiers) with hyphens are managed so that they can properly convert to Microsoft 365's format during a migration.

We added a clear error message in the case an unhandled exception stops your migration to Microsoft 365.
