Hi all.
is it possible to replace a data node from one server to another if the configuration and versions are the same?
or I have to reindex all the data in my node.
please suggest me.
Thank you.
I am not sure I fully understand your question, maybe you can outline the usecase a bit further.
Have you read the documentation about rolling upgrades? See https://www.elastic.co/guide/en/elasticsearch/reference/7.4/rolling-upgrades.html - this outlines how to stop a system, then install a new version. When you move the data and configuration to another physical node you can start the new ES process on that node as well.
