I followed the instruction [in this page](https://www.elastic.co/guide/en/kibana/current/migrating-6.0-index.html) to manually reindex the **Kibana index** to get ready to upgrade our Elasticsearch server from 5.6.7 to 6.x.

The first step (Set .kibana index to read-only) went ok, but I got an error message when performing the second step (Create .kibana-6 index). This is the console output I received:

{  
"error": {  
"root\_cause": [  
{  
"type": "parse\_exception",  
"reason": "Failed to parse content to map"  
}  
],  
"type": "parse\_exception",  
"reason": "Failed to parse content to map",  
"caused\_by": {  
"type": "json\_parse\_exception",  
"reason": "Unexpected character ('"' (code 34)): was expecting comma to separate Object entries\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@3d567acd; line: 5, column: 6]"  
}  
},  
"status": 400  
}

The command I ran is identical to the step 2 example in the instruction other than adding "index.format": 6 and "index.mapping.single\_type": true under settings. Please see the screenshot below.

How can I fix the issue? Thanks.
