Hi, I am trying to copy my index from one source to another source from a remote cluster. to follow this link > **[Migrating your Elasticsearch data | Elasticsearch Service Documentation |...](https://www.elastic.co/guide/en/cloud/current/ec-migrate-data.html#ec-migrate-data)** I got an error: my cluster is not on reindex.remote.whitelist. I were using - Elasticsearch (Self-Managed) – Azure Marketplace, I created 2 nodes of clusters succssefully. I did create a few blank indexes. I have another 2 nodes of clusters with full seeds indexes. Now, I want to copy the old one to new one. Please let me know how can I add the remote cluster to the new reindex.remote.whitelist. Thank you! Tom ---

Welcome. Can't you modify `elasticsearch.yml` configuration file? BTW did you look at [Cloud by Elastic](https://www.elastic.co/cloud)? It also runs on Azure. 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, Maps UI, Alerting and built-in solutions named [Observability](https://www.elastic.co/observability), [Security](https://www.elastic.co/security), [Enterprise Search](https://www.elastic.co/enterprise-search) and what is coming next 🙂 ... Everything in few clicks. ---

Please advise what would the steps I should take. Using cloud was just an advice. So depending on how you are running elasticsearch, the answer could be different. ---

Hi, I was able to modify elasticsearch.yml through PuTTY HHS. I did modify esdata-0 and esdat-1 to add reindex.remote.whitelist: oldhost:9200 then sudo -i service elasticsearch stop sudo -i service elasticsearch start stop/start elasticsearch after modification. However, my elasticsearch was not working at all. I was not able to make a connection to URL:9200. [http://url:9200/\_aliases?pretty=true](http://url:9200/_aliases?pretty=true) (Error: Request timed out) After deleted "reindex.remote.whitelist: oldhost:9200" from elasticsearch.yml, it works as before. Ayn idea??? Thank you! Tom ---
