### Step 1: Ensure Elasticsearch minimum requirements are met

MinIO requires a 5.x series version of Elasticsearch. This is the latest major release series. Elasticsearch provides version upgrade migration guidelines [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-upgrade.html).

### Step 2: Add Elasticsearch endpoint to MinIO

**Step 1: Export GSA Configuration**

Export your GSA configuration as XML. A typical GSA configuration includes:
- Collections with URL patterns
- Start URLs and crawl rules
- User agent settings
- Good/bad URL patterns

**Step 2: Import via Fess Admin UI**

1. Log in to Fess Admin Console: `http://<fess-server>:8080/admin`
