Hi,
I'm trying to reindex a 1.7.0 kibana index to 2.4.6 via the elasticsearch-migration plugin and am seeing the following error:
```
PUT /.kibana-2.4.6 failed with [400] Mapping definition for [_size] has unsupported parameters: [store : true]: {}
```
The mapping for \_size looks like this:
```
"_size" : {
"store" : true
},
```
How can I get the renidex to complete?
Regards,
D

`_size` has been replaced as a plugin in 2.x series.
[https://www.elastic.co/guide/en/elasticsearch/reference/2.4/breaking\_20\_removed\_features.html#\_literal\_\_size\_literal\_is\_now\_a\_plugin](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/breaking_20_removed_features.html#_literal__size_literal_is_now_a_plugin)
So if you are using it, you might have to install this may be.
I'm not familiar with that though and I don't recall how the migration plugin worked.
May be you could remove the field `_size` from the mapping?

I guess you need to do something like:
```auto
DELETE .kibana-2.4.6
PUT .kibana-2.4.6/_mapping
{
// Your mapping here
}
```
And then copy again the data from your old index to the new one.
But I'm really unsure here and I think you should better ask this in #kibana channel though.
May be move this thread there? (I can do it for you if you can't).
