Hi
I have a cluster with 4 nodes of Elasticsearch. 2 of them are in datacenter A and the other 2 are in datacenter B
Here is my concern:
I want to run an instance of each node in another datacenter. For example `node1` and `node2` are in A ,`node3` and `node4` are in B
I want to run an instance of `node1` in `node3` and run an instance of `node2` in `node4` and also run an instance of `node3` in `node1` and run an instance of `node4` in `node2`
How can I do this? What measures should be taken?
Best regards

I do not understand. What are you trying to achieve?

Thank you for your response
I want to make an instance of each node, just for sure, if one of datacenters breaks down, my cluster will be remains the same

You can not deploy a highly available Elasticsearch cluster across only 2 data centres. See [the docs](https://www.elastic.co/guide/en/elasticsearch/reference/7.11//high-availability-cluster-design.html) for further details.

Thank you so much
Ok, another point came to my mind:
It is about primary shard and it replica...
Imagine, there is a primary shard in `node1` and its replica is in `node2` (in 1 datacenter)
Hears the deal: How can I make more replica shard from a primary in `node1` and distribute it into `node3` and `node`4 ?
I hope I was able to convey my meaning to you
Thank you so much

Increase the number of replica shards. This is an index level setting.
