Hello!

I want to migrate some documents using remote reindex API from ES 1.x to ES5.1.2 and I have a weird problem:

- **Error** : mapper [field1] of different type, current\_type [keyword], merged\_type [long]
- **Error** : mapper [field2] cannot be changed from type [float] to [long]

The mappings in ES5 cluster are: _{"field1":{"type":"keyword"},"field2":{"type":"float"}}_ and the document that I want to reindex is _{"field1":1,"field2":2}_

Creating a document with exactly the same content using POST API works, but reindex fails.  
I don't have any coerce settings at index level or field level.

Thank you,

---

Bump.

It is really important, because otherwise I can't move all the data from one cluster to the other cluster.

Reindex task's response is:  
{..."response":{...  
"failures": [  
{  
"index": "index",  
"type": "default",  
"id": "AU0TIvm5KBq\_GySoOJRi",  
"cause": {  
"type": "illegal\_argument\_exception",  
"reason": "mapper [field1] of different type, current\_type [keyword], merged\_type [long]"  
},  
"status": 400  
},  
{  
"index": "index",  
"type": "default",  
"id": "AU0tz1N8KBq\_GySoDvr9",  
"cause": {  
"type": "illegal\_argument\_exception",  
"reason": "mapper [field2] cannot be changed from type [float] to [long]"  
},  
"status": 400  
}  
]  
}}}

Documents are:

- id: AU0TIvm5KBq\_GySoOJRi: {"field1":1}
- id: AU0tz1N8KBq\_GySoDvr9: {"field2":2}

Reindex request is:  
{  
"waitForCompletion": false,  
"body":{  
"conflicts": "proceed",  
"source": {  
"remote": { "host": "host"},  
"index":"index",  
"size": 1000,  
"type":"default"  
},  
"dest": {  
"index": "index"  
}  
}  
}

Thank you
