Update field mappings template in created index under an alias

问题

I have deployed a template in AWS ElasticSearch named users-version-1-order-1, and indexed data under users-all index which is searchable via users alias.

So, all documents are always indexed and updated in users-all, how do I deal with schema change moving forward with applying a new template version? e.g. PUT users-version-2-order-2 and apply it to users-all index.

[UPDATE]

{
  "index_patterns": "users*",
  "order": 6,
  "version": 6,
  "aliases": {
    "users": {}
  },
  "settings": {
    "number_of_shards": 5
  },
  "mappings": {
    "_doc": {
      "dynamic": "strict",
      "properties": {
        "id": { "type": "keyword" },
        "emailAddress": { "type": "keyword" }
      }
    }
  }
}
