+## Duplicate Mappings
+
+You can use the Duplicate Mappings feature to create an exact copy of a mapping. The duplicated mapping has the same configurations and enrichments as your original mapping. 
+
+Duplicate Mappings supports [Actions destinations](#actions-destination), [Reverse ETL destinations](/docs/connections/reverse-etl/reverse-etl-catalog), and destinations connected to Engage [Audiences](/docs/engage/audiences) and [Journeys](/docs/engage/journeys).  
+
+To duplicate your mappings: 
+
+1. Navigate to **Connections > Destinations** and select the destination with the mappings you'd like to copy. 
+2. On the destination's **Mappings** tab, select the menu button (**...**) and click **Duplicate Mapping**. 
+3. Review the popup and click **Duplicate Mapping**.
+
+Segment creates a disabled mapping with the name "Original Mapping Name (Copy)". You must enable the mapping for data to flow.

 When you set up destination actions in Reverse ETL, depending on the destination, some [mapping fields](/docs/connections/reverse-etl/setup/#step-4-create-mappings) may require data as an [object](/docs/connections/reverse-etl/manage-retl/#object-mapping) or [array](/docs/connections/reverse-etl/manage-retl/#array-mapping).
