Search head and Search Head Cluster to indexer server.

[dustymehul]

We have a single Search Head Node which works over a Indexer Cluster.
All Configurations like users, roles, Dashboards etc are present on this Node.

We are now looking to create a Search Head cluster over the Indexer Cluster.
Mean while we set up the Search Head cluster, i want to keep the first node up and running as it is under use.

Question 1 - Is it possible to have an "individual node" and a "Search Head Cluster" running over an Indexer Cluster together?

Once Search Head Cluster is completely up, we plan to add the first remaining node as well in the cluster.

Question 2 - How to replicate all the existing configurations from this Node to Search Head Cluster. My understanding is that when we add a SH Node to SH Cluster, all the existing Configurations will be lost from the SH Node. And SH captain will push the cluster configuration to the newly added node. How to retain/replicate them to all servers of SH Cluster before adding the node?

Answer 1 - Yes.

Answer 2 - If the individual node is not part of the SHC then the deployer will not touch it (it won't even know the node exists). Otherwise, you should copy the SH Node configs to the cluster before adding the node.

Thanks a Lot @richgalloway . Can you please share some reference links/pages where i can read about copying the SH Node configs to the cluster.
