Whitelist in AWS Elastic Search 6.5.4 host

Hello,
I'm trying to upgrade a 2.3 cluster to 6.5.4 by creating a new cluster of 6.5.4 and trying to pull the documents from the old 2.3.
I'm following this guide:
https://www.elastic.co/guide/en/elasticsearch/reference/6.0/reindex-upgrade-remote.html
Unable to whitelist, since it's AWS and there no yml files.
Is there a curl command to add the whitelist setting or is not possible at all on AWS?

You should probably ask is AWS forums.

BTW did you look at https://www.elastic.co/cloud and https://aws.amazon.com/marketplace/pp/B01N6YCISK ?

Cloud by elastic is one way to have access to all features, all managed by us. Think about what is there yet like Security, Monitoring, Reporting, SQL, Canvas, APM, Logs UI, Infra UI, SIEM, Maps UI and what is coming next :slight_smile: ...
