Hello there,

Following log entry is appearing in kibana logs. I understand this is because of previous kibana versions. can I delete these indexes? Will deleting this affect my cluster?

You can delete it.

I just deleted bunch of .kibana index just make sure you keep your current version index as is.

you can check aliases and _cat/aliases and see where your existing .kibana is pointing to (just incase if you want to check)
