Best practice in making data nodes as master nodes

Elastic Stack Elasticsearch

Hi gurus,

I want to know what is the best practice to make data nodes in cluster1 as master nodes in cluster2. We are shutting down cluster1 and moving the nodes to cluster2.

Should I snapshot, delete and restore the data from cluster1 to cluster2? How to handle system indices like .kibana created in cluster2?

Thanks in advance.

You can just snapshot cluster1 and then restore to cluster2. Leave cluster1 up to ensure that restore operation worked and you are not missing data. Also look up restore settings to speed up restore processes like turning off replicas.

You can just delete .kibana index in cluster2 before you restore.
