I have some splunk indexers running on Physical Windows 2016 servers and 4 TB of index data on each (local storage). The replication factor is thus 2 and all infra is healthy.
I need to upgrade to Windows 2019 or later and I'm thinking of and in-place Windows upgrade on each indexer in turn.
Has anyone done similar in the past and have any caveats/battles scars to share?
