Hello,  
I am trying to migrate from ES and Kibana 5.6.7 versions to 6.2.3. The problem occurs when i am reindexing the .kibana index to a nex .kibana-6 index.  
Following the migrating kibana index to 6.x procedure, when i try to execute the following:

POST \_reindex  
{  
"source": {  
"index": ".kibana"  
},  
"dest": {  
"index": ".kibana-6"  
},  
"script": {  
"inline": "ctx.\_source = [ctx.\_type : ctx.\_source]; ctx.\_source.type = ctx.\_type; ctx.\_id = ctx.\_type + ":" + ctx.\_id; ctx.\_type = "doc"; ",  
"lang": "painless"  
}  
}

i get a time out error:

{  
"statusCode": 504,  
"error": "Gateway Time-out",  
"message": "Client request timeout"  
}

I tried to execute it on a commande console with no success.  
Is this error familiar to anyone?

Hi @mrnotsmartone,

What is the size of your .kibana index? You can see this by querying `_cat/indices`
