#### Document Migration

**Step 1: Export from Source**

Export documents from your existing Elasticsearch/OpenSearch cluster:

```bash
# Using elasticdump
elasticdump \
  --input=http://old-es-server:9200/my-index \
  --output=documents.json \
  --type=data
```

**Step 2: Convert to Fess Format**

Transform documents to include Fess required fields. Example transformation script:

```python

,m[g]=s*y,m.willChange=c+', '+g}var E={"x-placement":e.placement};return e.attributes=le({},E,e.attributes),e.styles=le({},m,e.styles),e.arrowStyles=le({},e.offsets.arrow,e.arrowStyles),e},gpuAcceleration:!0,x:'bottom',y:'right'},applyStyle:{order:900,enabled:!0,fn:function(e){return V(e.instance.popper,e.styles),j(e.instance.popper,e.attributes),e.arrowElement&&Object.keys(e.arrowStyles).length&&V(e.arrowElement,e.arrowStyles),e},onLoad:function(e,t,o,n,i){var r=L(i,t,e,o.positionFixed),p=O(o.p...

=== ":material-language-kotlin: Kotlin"
    ```kotlin

MINIO_NOTIFY_ELASTICSEARCH_PASSWORD     (string)             password for Elasticsearch basic-auth
MINIO_NOTIFY_ELASTICSEARCH_COMMENT      (sentence)           optionally add a comment to this setting
```

For example: `http://localhost:9200` or with authentication info `http://elastic:MagicWord@127.0.0.1:9200`.
