Question

Hello team. I get the error below when creating new azure migrate project:

{

"status": "Failed",

"error": {

    "code": "DeploymentFailed",

    "message": "At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/arm-deployment-operations for usage details.",

    "details": [{

            "code": "Conflict",

            "message": "{\r\n  \"status\": \"Failed\",\r\n  \"error\": {\r\n    \"code\": \"ResourceDeploymentFailure\",\r\n    \"message\": \"The resource write operation failed to complete successfully, because it reached terminal provisioning state 'Failed'.\",\r\n    \"details\": [\r\n      {\r\n        \"code\": \"InternalServerError\",\r\n        \"message\": \"An error occurred.\",\r\n        \"details\": []\r\n      }\r\n    ]\r\n  }\r\n}"

        }

    ]

}

}

{

"status": "Failed",

"error": {

    "code": "InternalServerError",

    "message": "An error occurred.",  
    "details": []

}

}

After reviewing all Azure Policy assignments at both the subscription and resource‑group levels, I haven’t found any policy that would block this deployment. For context, I successfully created an Azure Migrate project two days ago and then deleted it, but since yesterday every attempt to provision a new project has been failing during the private‑endpoint creation phase. Could we take a closer look together to identify any residual artifacts or conflicts that might be preventing the deployment?

Hi Amjed Saidani,

you're encountering an error during the ARM deployment in your Azure Migrate project.

The error message indicates that at least one resource deployment operation failed due to conflict or an internal server error, check the below steps to resolve the issue.

The failure could be due to a transient error. Attempt to redeploy the project by selecting Re-deploy in the Deployments section.

If you are deploying in a newly added geography, it may take some time before the deployment can succeed. Wait a short while and try again.

The error message mentions a conflict and an internal server error. Look for more detailed error messages in the deployment operations to understand the root cause.

Common causes of conflicts include resource name conflicts, resource locks, or dependencies on other resources that are not yet provisioned.

Check the detailed error messages provided during the deployment process for more specific guidance on what might be causing the failure.

Hi Mohan Krishna T Sreeramulu,
Thank you so much for your help but really it doesn't work. And as a mentioned before, the problem that i have is an error "conflict": it's like there is something linked with the deleted project but really i couldn't find any trace and the log is not so clear and no more details.
