# Replace a Semantic Model with an Extended Semantic Model

When you extend a semantic model with additional calculations, data objects, or modified relationships, you can update an existing visualization with the latest data from the extended version.Tableau Next automatically maps matching fields based on API name, object name, and data type.

1. From the semantic model’s context menu in the visualization, click **Replace Semantic Model**.
2. Select the extended semantic model and click **Replace**.
    
    Existing mappings are preserved when matching fields are found. New fields from the extended semantic model are also available for analysis.
3. If Tableau Next doesn’t map a field automatically, drag the corresponding field from the extended semantic model to replace it in the visualization.
