Duplicate a data view
Duplicating a data view gives you an editable copy to work from. This is useful whenever you want to reuse an existing data view as a starting point, for example to try out different field formatting or a different index pattern without affecting the original, or to make a similar data view for another use case.
You need the same privileges required to create a data view, and an existing data view to duplicate.
Open the Kibana application where you want to use the data view, for example Discover or Lens.
NoteDuplication isn't available from the Data Views management page.
In the data view selection menu, select the data view that you want to duplicate.
Still in the data view selection menu, select Manage this data view. A flyout with more details about the data view opens. For a managed data view, it indicates that you can't edit it directly.

Select Duplicate. A similar flyout opens where you can adjust the settings of the new copy.
Finalize your edits, then select Save data view to Kibana or Use without saving, depending on your needs.
If you save it to Kibana, the new, editable data view appears in the data view selection menu and on the Data Views management page, separate from the one you duplicated.
