+(Required, string)
+Name of the index alias to convert to a data stream. The alias must meet the
+following criteria:
+
+- The alias must have a <<aliases-write-index,write index>>.
+- All indices for the alias have a `@timestamp` field mapping of a `date` or `date_nanos` field type.
+- The alias must not have any <<filtered,filters>>.
+- The alias must not use <<aliases-routing,custom routing>>.
+
+If successful, the request removes the alias and creates a data stream with the
+same name. The alias's indices become hidden backing indices for the stream. The
+alias's write index becomes the stream's write index.
