Hi all
I have a question before upgrading elastic to 8.x
Do i have to upgrade all logstash and filebeat node to version 8.x or it can be keep at version 7.17
Since there is a lot of logstash and filebeat node in my system so upgrading them will take a lot of time which i'm not sure i have.
If i dont have to update then will the be any issue can be cause by logstash in the version 7.17 to elastic 8.x
Thanks for your time
