How to: Remove (Uninstall) a Model

Applies To: Microsoft Dynamics AX 2012 R3, Microsoft Dynamics AX 2012 R2, Microsoft Dynamics AX 2012 Feature Pack, Microsoft Dynamics AX 2012

You can remove a model from a model store. However, we recommend that you remove a model only if you want to permanently delete it.

You can use either Windows PowerShell cmdlets or the AXUtil command-line utility to perform this task.

Warning

Deletion of a model or layer may cause significant loss of business data, and also loss of metadata. When you run a command to delete a model, we recommend that you use the –Details or /verbose parameter to list the elements that may be deleted. In this way, you can determine the effect of the deletion on your environment.

• Business data may be lost if the database schema is changed. The database schema is changed when tables or fields are removed.

• Element IDs may be lost. If element IDs are lost, existing business data may become invalid.

• Orphaned metadata elements in other models or layers are deleted.

If you want to upgrade a model or replace a model with a newer version, we recommend that you import the model over the existing model. For more information about how to import models, see How to: Export and Import a Model. We recommend this approach, because element IDs and element handles are assigned at installation. Therefore, if you delete a model, and then reimport that model or a newer version of it, element IDs and element handles are randomized, and data integrity can be affected. For more information about element IDs and element handles, see Maintaining Installation-Specific Element IDs and Element Handles.

Validate permissions

• Validate that you have appropriate permissions to work with the model store:

  • Administrative permissions on the local computer

  • System Administrator rights in Microsoft Dynamics AX

  • In Microsoft SQL Server:

    • Membership in the Securityadmin server role on the SQL Server instance

    • Membership in the db_owner role in the Microsoft Dynamics AX database
