How to migrate configurations from one cluster to other cluster?

[#1]

I am building a cluster similar to existing cluster, the application specific configurations as in the existing cluster should be reflected in my new cluster. Do we have some approach for the same?

Thanks in advance.

Ambari Blueprint can be a best approach to create new clusters based on the blueprint template.

A blueprint can be created by hand or can be created by exporting a blueprint from an existing cluster and then later you can reuse the same blueprint to create other clusters with the same configurations.

@Jay Kumar SenSharma thank you ,,,

what if we aren't doing the cluster rebuild using the blueprint method??

in such cases , how do we migrate the configurations only..
