    Data extraction failed during upgrade to Umbraco 7.10.0

    Hi all, my upgrade from dev to live is failing because of a collision.

    What's the best way to address this?

    Error report below:

      Exception:
    Umbraco.Deploy.Exceptions.ArtifactCollisionException: Some artifacts collide on unique identifiers.
    This means that they have different Udis, yet
    they refer to the same unique Umbraco object
    and therefore cannot be processed.

    Hi Colm,

    First of all sorry to hear that you have hit into data extraction failed during upgrade to Umbraco 7.10.0

    To solve the data extraction failed have a look at this documentation

    https://our.umbraco.org/documentation/Umbraco-Cloud/Troubleshooting/Structure-Error/#troubleshooting-structure-deploymentrestore-errors

    In the example its with a document type, but you can use the same method for data types.

    The main cause of this problem is when a Document Type (or Media Type, Data Type, etc) is manually created in two environments using the same alias.

    If you have two or more Cloud environments, we recommend that you never create or make schema changes directly on the Live or Staging environments. You should work with schema only in your Development environment or even better, your local clone of the project.

    Hope this helps,

    /Dennis
