# Copy rules

> Copy the rules of an index to another index on the same app.

export const Legacy = ({title, href}) => {
  return <Note>

    This page documents an earlier version of the API client.
    For the latest version, see <a href={href}>{title}</a>.

    </Note>;
};

<Legacy title="Copy or move an index" href="/doc/libraries/sdk/methods/search/operation-index" />

**Required ACL:** `editSettings`

This removes all index rules currently present in the destination index,
and replaces them with the rules from the source.
