I have the ES cluster with 9 shards and replicas, where all the data is stored locally on the nodes. We have the process complete data migration from one system to another. Since introduction of ES - we need to be able to migrate also ES indices. We are using Netapp snap-mirror mechanism for the rest of the data. What would be the best practice, so, when the second system starts it will actually build the cluster from migrated data. Thank you, Pasha -- ---

Hello Pasha, I'm not sure I fully understand what you're trying to achieve. So you want to migrate ES indices from one node to another, in case a node goes down? Or from one cluster to another, or? Basically, I don't get what you mean by "system". ## Best regards, Radu [http://sematext.com/](http://sematext.com/) -- Elasticsearch -- Solr -- Lucene On Mon, Nov 5, 2012 at 9:36 AM, Pasha [pavel.cuno@gmail.com](mailto:pavel.cuno@gmail.com) wrote: > I have the ES cluster with 9 shards and replicas, where all the data is > stored locally on the nodes.
