I am looking for options to automate the upgrade of Add-on in Clustered environment
Say for example, I have this add-on Splunk_TA_nix in SHCluster (which we have one deployer and 3 search head members)
Now I want to upgrade this add-on without breaking any custom configuration through automation (Instead of taking backup of folder, placing the new version of app and restoring the custom configuration to new version)
Please help to identify the best and automated way to upgrade Add-on
