Hi All,
By mistake I added a wrong mapping as below
```
"person_info" : {
"_timestamp" : {
"enabled" : true,
"store" : true
},
"properties" : {
"entry_time" : {
"type" : "date",
"format" : "dateOptionalTime"
},
"address" : {
"properties" : {
"local_address" : {
"properties" : {
"street" : {
"type" : "string"
},
"city" : {
"type" : "string"
},
"zip" : {
"type" : "string"
}
}
"local_address" : {
"properties" : {
"street" : {
"type" : "string"
},
"city" : {
"type" : "string"
},
"zip" : {
"type" : "long"
}
}
}
}
}
}
}
}
```
where zip is string in one mapping and long in another. Is there any way to remove any one of the mapping?
Regards,

Once mapping have created , can not be modified manually

I don't mind losing one of the mapping data. What is the best way to to migrate to 2.2 from 1.7? For sure I will get mapping exception if I move to 2.2

You can use the Elasticsearch Migration Plugin to check whether you can safely upgrade.

It says I cannot upgrade.
```
Conflicting field mappings
Mapping for field myindex_type1:person_info.address.zip conflicts with: myindex_type2:person_info.address.zip. Check parameter: type
```

Is there any way to fix this through code? I can delete the index type but not whole index. How can I remove one of the mapping?

There is no other way than reindexing. This means creating a new index with proper mapping and reindexing all the documents, deleting your old index afterwards.

That's gonna be pain since this is already deployed in multiple environment. I wish there was a way to convert all the improper data type to string globally if we don't care about aggregation.

Not when I have TB's of data and minimal down time 🙂
