Hello Team Currently, I'm running 2 instances having Elasticsearch Independently. Now, I've to build a 3 node cluster which should include the available two nodes. what's the best way to do that(without losing the data) ? Please suggest Thanks for your time as always 🙂 ---

Do you mean that you have: 1. 2 clusters with one node per cluster 2. 1 cluster with 2 nodes? If `1`, I'd suggest to start a new node with the same cluster name than node1 or node2 and then do a reindex from remote or a snapshot/restore from node2 or node1. If `2`, just start the new node, make it join the cluster and you're done. ---

hello @dadoonet I don't have cluster. I'm running the 2 nodes Independently. Now, I want to join them and form a cluster ---

So do this: > I'd suggest to start a new node with the same cluster name than node1 or node2 and then do a reindex from remote or a snapshot/restore from node2 or node1. ---

I've many indices in node 1 and node2. do I've to reindex each individually? ---

Then snapshot and restore is the best option I believe. ---
