Can I update analyzer in field without recreating the index?

Following index is created.

 "ticketId": {
        "type": "text",
        "fields": {
          "completion": {
            "type": "completion",
            "analyzer": "simple",
            "preserve_separators": true,
            "preserve_position_increments": true,
            "max_input_length": 50,
            "contexts": [
              {
                "name": "mailboxIdStr",
                "type": "CATEGORY",
                "path": "mailboxIdStr"
              }
            ]
          },
          "keyword": {
            "type": "keyword"
          }
        },
        "analyzer": "simple"
      }
  

so, i want to update or remove "analyzer":"simple" from ticketId field. is it possible without recreate index or any other way?

You need to recreate the index. And reindex the data.
