Hello Team,

As per the document , first we need to take a backup of elaticsearch.yml, the elasticsearch.yml file in the current 8 version looks different.

> **[Different CA | Elastic Docs](https://www.elastic.co/docs/deploy-manage/security/different-ca)**

> If you have to trust a new CA from your organization, or you need to generate a new CA yourself, instruct your nodes to trust the new CA and then use...

# Enable security features

xpack.security.enabled: true

xpack.security.enrollment.enabled: true

# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents

xpack.security.http.ssl:  
enabled: true  
keystore.path: certs/http.p12

# Enable encryption and mutual authentication between cluster nodes

xpack.security.transport.ssl:  
enabled: true  
verification\_mode: certificate  
keystore.path: certs/transport.p12  
truststore.path: certs/transport.p12

Please advise is the document is correct we have single file for transport layer in keystore and trust store, but in the document they mentioned two different files.
