How to Migrate Microsoft Stream Classic Videos Post-Deadline
Question details
The user needs a method to bulk download or migrate approximately 400 GB of Microsoft Stream Classic videos after the official migration tool deadline has passed.
- Product
- Microsoft Stream
- Device & OS
- not provided
- Scenario
- An organization missed the Microsoft Stream Classic migration deadline and needs to retrieve a large volume of video data efficiently.
- Observed behavior
- Administrators still have access to the video content, but downloading the videos individually is highly inefficient, and the built-in migration tool is no longer available.
Verify that you have Global Administrator or Stream Administrator privileges and confirm your organization's current data retention policies with Microsoft Support.
Automate Bulk Downloads Using Power Automate and APIs
Since the built-in migration tool is no longer available, building a custom automation workflow is the most efficient way to extract a large volume of video files.
Once the official Microsoft Stream Classic migration period ends, standard bulk-download features are typically deprecated. However, administrators can often still interact with the underlying data via APIs.
By leveraging Microsoft Power Automate, you can create a custom flow to iterate through your Stream Classic library, download the raw video files, and automatically upload them to your new SharePoint or OneDrive environment.
Visit the Microsoft Power Automate Community forums to search for existing automation scripts or request guidance on creating a flow for Stream Classic bulk downloads.
Ensure that your administrative account has the necessary API permissions to access legacy Stream content and that Microsoft has not restricted the specific endpoints required for downloading.
Set up a custom Power Automate flow that retrieves video metadata, downloads the corresponding .mp4 files, and saves them to a designated SharePoint document library.
Before running the extraction script across the entire 400 GB library, confirm with Microsoft Support that your method complies with current service terms and retention requirements.
Manually Download High-Priority Videos
If API automation is not feasible for your organization, you can manually prioritize and download the most critical videos.

Frequently Asked Questions
Can I still use the official Microsoft Stream migration tool after the deadline?
Once the migration deadline has passed and the tool is retired by Microsoft, it is typically removed from the admin center. You will need to rely on custom API workflows or manual downloads to retrieve your data.
Will Microsoft delete my Stream Classic videos immediately after the deadline?
Microsoft enforces specific data retention policies for deprecated services. While administrators may have a short grace period where access is still possible, the data is subject to permanent deletion once that period expires.
Where should I store the videos once I download them from Stream Classic?
The recommended destination for migrated enterprise videos is SharePoint or OneDrive for Business, which integrate seamlessly with the new Microsoft Stream (on SharePoint) experience.
Where can I find API scripts for bulk downloading Microsoft Stream videos?
The Microsoft Power Automate Community (powerusers.microsoft.com) is the best resource for finding API solutions, custom automation flows, and scripts shared by other IT administrators.
