+Similar to `copy_collection` but a different database is used as the source for all cards used in the collection.  
+This comes in handy when you want to duplicate your whole collection to another one while changing datasource for all its cards.

+Similar to `copy_dashboard` but a different database is used as the source for all cards used in the dashboard.  
+This comes in handy when you want to duplicate your dashboard (and its cards) to another collection while changing datasource (e.g. multi-tenant application or different environments)

+Similar to `clone_card` but a different database is used as the source for all cards used in the dashboard.  
+Used by `clone_dashboard_new_database`, it clone recursively clone linked cards (i.e. when your question reference another one) to a destination collection while changing their data source

 - #### `update_column`
 Update the column in Data Model by providing the relevant parameter (list of all parameters can be found [here](https://www.metabase.com/docs/latest/api-documentation.html#put-apifieldid)).  
 For example to change the column type to 'Category', we can use:
