I'm attempting to migrate our on-premises Azure DevOps Server to a cloud Azure DevOps Service.

I've run the DataMigrationTool but am getting the error:

Validation completed 'Validate File Content Consistency' with result Failed, message VS403310: An inconsistency was detected in some of the files in the collection. This inconsistency needs to be corrected prior to running an import to Azure DevOps Services.

There's nothing particularly useful in the logs, nor can I find much online and the Azure DevOps Services virtual support assistant doesn't have a clue.

Don't suppose anyone's encountered this before and could point me in the right directon?

  • What is your current on-prem Azure DevOps Server/TFS version? Including the update version. The tags just say 2020, not 2020 RTM/2020.1/etc. – Daniel Mann Sep 06 '22 at 16:25
  • It's Azure DevOps Server 2020 Update 1.2 (18.181.32404.7) but I couldn't find a pre-existing tag for this & I've not got priv to create my own yet. – mattho Sep 07 '22 at 17:10

Firstly, there was several events on 9/5 that would impact import process. The events have been fixed now. So if you had this issue around the 9/5, please try again to check if the issue has disappeared.

If not, when encountering VS403310 error, you need to contact Azure DevOps customer support (not virtual support) to get more detailed information. This is documented here.

Here are the detailed steps to create customer support ticket:

  1. You need to have an active Azure subscription. Then, click this link and select "Request Support" under "Basic".

  2. Sign in with your account and you will be re-direct to Azure portal. Click "Create a support request".

  3. Fill in the form in "Problem description" tab. You can fill in some blank with the information below:

    Issue type: Technical

    Service: Azure DevOps Services Summary: Migrating to Azure DevOps Service. DataMigrationTool error - VS403310: An inconsistency was detected in some of the files in the collection

    Problem type: Configuring Azure DevOps Services

    Problem subtype: Migrating from Azure DevOps Server or TFS

  4. Click "Next" to "Additional details" tab. Briefly describe your problem and provide import ID. After that you need to fill in some basic questions like work time zone. Then click "Next" and "Review + Create" to create a support ticket.

Microsoft services will contact you through contact information you have left. The response time for tickets in severity C is 8 working hours, and for severity B is 4 working hours.

  • Thanks Jane, I have gone this route and had a really length set of DB queries to run, just not had time to run thru yet. – mattho Sep 07 '22 at 17:05
