Hi All,

I have two different cluster ES 1.4.4 and ES 2.4.0 , want to migrate single index (250GB) from old cluster to new cluster with default mapping and settings. Any Suggestion.

Do an in place upgrade, or use snapshot and restore?

Why not upgrade to 5.X?

Hi

How about Logstash Input / Output elasticsearch Plugin?

[https://www.elastic.co/guide/en/logstash/2.4/plugins-inputs-elasticsearch.html](https://www.elastic.co/guide/en/logstash/2.4/plugins-inputs-elasticsearch.html)  
[https://www.elastic.co/guide/en/logstash/2.4/plugins-outputs-elasticsearch.html](https://www.elastic.co/guide/en/logstash/2.4/plugins-outputs-elasticsearch.html)

But I don't know much about version dependency, sorry.

Thanks Makoto. I am trying to re-index using Logstash Input / Output elasticsearch Plugin but frequently getting SearchContextMissingException.

--  
input {  
elasticsearch {  
hosts =\> "sourceip:9200" # A  
index =\> "testindex"  
query =\> '{ "query": { "match\_all": {} } }'  
size =\> 5000  
scroll =\> "20m"  
docinfo =\> true

}  
}  
filter {  
mutate{  
remove\_field =\> ["@version","@timestamp"]  
}  
}  
output {  
elasticsearch {  
hosts =\> "destip:9200" # B  
index =\> "%{[@metadata][\_index]}"  
document\_type =\> "%{[@metadata][\_type]}"  
document\_id =\> "%{[@metadata][\_id]}"  
}  
}
