Migrate data from current production Elasticsearch nodes to a new hardware

Elastic Stack Elasticsearch
1

Hi,

I am currently running ES (version 7.5.1) three nodes in the cluster mode.

ES Node1:- 192.168.0.10
ES Node2 :- 192.168.0.11
ES Node3 :- 192.168.0.12

I want to migrate the data from the above running production cluster to new hardware in cluster mode whose IP details are as below.

ES Node1:- 172.16.1.10
ES Node2 :- 172.16.1.11
ES Node3:- 172.16.1.12

Is there an elegant and efficient way to copy the data from the current production ES Cluster ( 3 nodes) to the new hardware based ES Cluster ( 3 nodes). Any help will be highly appreciated and I look forward to hearing from you. Thanks in advance.

Best Regards,

Kaushal

Some questions:

  1. Is the new cluster in the same premise?
  2. Do you need the same cluster name or different name?

Because no 1 in No, it means you need to have big pipe if want to use the solution that I ever done.
what I've done is add one by one the new server into existing cluster, modify the node type then after all new nodes as a member of the cluster, the old one will fade one by one.
