how to move elasticsearch data from one server to another

Question

How do I move Elasticsearch data from one server to another?

I have server A running Elasticsearch 1.1.1 on one local node with mul

Answer 1

If you can add the second server to cluster, you may do this:

1. Add Server B to cluster with Server A
2. Increment number of replicas for indices
3. ES will automatically copy indices to server B
4. Close server A
5. Decrement number of replicas for indices

This will only work if number of replaces equal to number of nodes.
