I need to upgrade filebeat 6.8 to 7.16 and winlogbeat 6.3 to 7.16. After reading the upgrade guide, my understanding is that I need to upgrade winlogbeat to 6.8 first, then load index template.
However our beats output to logstash, not elaticsearch. Do we still load index template? How can I do that when we don't have a running Elasticsearch cluster?
Thank you.
