Hu, I'm trying to copy some indices from one Elasticsearch instance to another. I'm trying top copy this index called "tagindex_v2".  I've used http://localhost:9400/tagindex_v2 and in the body i've copied the json,

{
    "tagindex_v2": {
        "aliases": {},

I get this error

{
    "error": {
        "root_cause": [
            {
                "type": "parse_exception",
                "reason": "unknown key [tagindex_v2] for create index"
            }
        ],
        "type": "parse_exception",
        "reason": "unknown key [tagindex_v2] for create index"
    },
    "status": 400
}

Can someone please tell me how i should fix this? I'm simply copying JSON content from an existing index from a different instance and creating it here.

Thanks in advance

You need to take only what's located inside the tagindex_v2 key, i.e.

{
    "aliases": {},
    "mappings": {
        "properties": {
            "deprecated": {
                "type": "boolean"
            },
            ...
        }
    },
    "settings": {
        "index": {
            "max_ngram_diff": "17",
            ...
    }
}

You also need to remove the following properties from the settings section:

• provided_name
• creation_date
• uuid
• version
