Elastic Search
We are relatively new to Elastic Search and are currently running one ES 6.1.2_03 server in our PeopleTools 8.57 environment. We are adding two additional servers to create a three-node cluster. We'd like to implement the latest version (ES 6.1.2_05) on the new servers. My question - How would we go about upgrading the existing ES 6.1.2_03 to 05 ? Would we need to uninstall current and reinstall new ? can we upgrade what's there ?
