Hi,  
I have a running elaticsearch cluster comprised of two (02) nodes (both master and data).  
I wish to migrate my database to a new cluster comprised of seven (07) nodes (3 Master nodes, 2 Data nodes, 1 Coordinator node and 1 ingest node).

```
 What is the best way to proceede to migrate the database and preserve the indices so I can use the new cluster with my old Kibana node (Use the old dashboards).

```

Thanks in advance..

I'm not sure what "stage" you are in, but if you new nodes don't yet exist or can be destroyed, I would ADD the new nodes to the existing cluster and eventually turn off the old nodes after the data migration is done by elastic.

Doc: [Add and remove nodes in your cluster | Elasticsearch Guide [7.13] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/add-elasticsearch-nodes.html)

Welcome to our community! 😃

That would be the simplest, if you can do it!  
Otherwise you can use snapshot and restore, or a remote reindex.
