I need to move my SharePoint site to SharePoint online - I am trying to use the migration tool from teh following link - https://spmt.sharepointonline.com/betainstall/default.htm . I get the main screen and when I click on install, I receive the following message -

This XML file does not appear to have any style information associated with it. The document tree is shown below.

<Error>

<Code>ContainerNotFound</Code>

<Message>The specified container does not exist. RequestId:3dc491e2-a01e-0002-22e7-6ac45c000000 Time:2026-11-02T16:30:16.3614602Z</Message>

</Error>

Is the migration tool no longer available for use?

    The SharePoint Migration Tool is still available; install the General Availability release from Microsoft’s current SPMT installation page instead of the failing betainstall URL.

    Install the supported release

    1. Open the canonical Microsoft installation page:
      Step 1: Install the SharePoint Migration Tool (SPMT)
    2. Under Download and install, select General Availability — Install here.
    3. Alternatively, use Microsoft’s documented GA redirect directly:
      https://aka.ms/spmt-ga-page
    4. Complete the installation and start SPMT.

    Microsoft’s current release notes list SPMT build [IP Address] for General Availability, first release, and public preview, confirming that SPMT has not been withdrawn.^1^

    The ContainerNotFound response indicates that the beta URL is currently resolving to a missing or unavailable Microsoft-hosted storage container. It does not, by itself, mean the migration tool has been discontinued.

    If the GA installer also fails

    1. Test the GA link in another browser or network to rule out proxy or firewall interception.
    2. Ask the network administrator to allow the documented SPMT installation endpoints, particularly:
      • https://spmt.sharepointonline.com
      • https://spmtreleasescus.blob.core.windows.net
      • Microsoft authentication and Azure Storage endpoints listed in the prerequisites.^2^
    3. Verify that the computer is 64-bit Windows and has .NET Framework 4.6.2 or later. Microsoft also identifies the x64 Visual C++ Redistributable as a possible installation dependency.^3^
    4. If the official GA link fails from multiple devices and networks, check Microsoft 365 admin center → Health → Service health, then open a Microsoft 365 support request and include:
      • The ContainerNotFound response
      • Timestamp and request ID
      • The GA and preview URLs tested
      • Results from different networks/devices

    The public-preview redirect, https://aka.ms/spmt-beta-page, is a supported fallback, but it may still reach the affected beta installer resource. Use the GA installer first.^4^

    Hi Denise,

    The ContainerNotFound error suggests that the beta installer URL is pointing to a missing or unavailable Azure Storage container. It does not necessarily mean that the SharePoint Migration Tool (SPMT) has been discontinued.

    Microsoft still provides SPMT through its official installation page:

    https://learn.microsoft.com/en-us/sharepointmigration/how-to-use-the-sharepoint-migration-tool

    I recommend trying General Availability → Install here rather than the old beta installation link.

    If that also fails, please note that another user reported similar installer problems on 30 October 2026.

    You can then raise a Microsoft 365 support request and provide the ContainerNotFound error, Request ID, timestamp and the URLs tested. This should help Microsoft investigate whether an installation resource is unavailable.

    Official troubleshooting documentation:

    https://learn.microsoft.com/en-us/sharepointmigration/spmt-install-issues

    I hope this helps.
