I'm trying to change a document from this. Is this possible?

{  
"zenoss01.hostname": {  
"issued\_to": null,  
"cert\_sans": "",  
"valid\_till": "2021-01-17",  
"valid\_from": "2016-01-18",  
"issuer\_ou": null,  
"days\_left": 364,  
"cert\_ver": 2,  
"cert\_alg": "sha256WithRSAEncryption",  
"issued\_o": "Zenoss",  
"cert\_exp": false,  
"cert\_sha1": "83:E4:4B:8B:DF:E4:72:78:A3:7B:24:99:96:1D:6A:C6:ED:67:A5:8E",  
"issuer\_c": "US",  
"issuer\_cn": null,  
"issuer\_o": "Zenoss",  
"validity\_days": 1826,  
"cert\_sn": "15935028744769600013"  
}  
}

To this.

{  
"hostname": "zenoss01.hostname"  
"issued\_to": null,  
"cert\_sans": "",  
"valid\_till": "2021-01-17",  
"valid\_from": "2016-01-18",  
"issuer\_ou": null,  
"days\_left": 364,  
"cert\_ver": 2,  
"cert\_alg": "sha256WithRSAEncryption",  
"issued\_o": "Zenoss",  
"cert\_exp": false,  
"cert\_sha1": "83:E4:4B:8B:DF:E4:72:78:A3:7B:24:99:96:1D:6A:C6:ED:67:A5:8E",  
"issuer\_c": "US",  
"issuer\_cn": null,  
"issuer\_o": "Zenoss",  
"validity\_days": 1826,  
"cert\_sn": "15935028744769600013"  
}

You can move fields to the top level using something like [this](https://discuss.elastic.co/t/how-to-dynamically-move-nested-key-value-to-root-level/180006/2).
