Hello there! I'd like to update my ELK stack to version 7.1. Still, i don't understand whether i have to turn off beats, forwarders etc.. When upgrading logstash. Assuming that i have _6 instances of logstash_ , behind a load balancer, and that there are no issues about the template i'm using, and that any of the breaking changes wouldn't affect my pipeline. Will upgrading the 6 logstash nodes _one at a time_ , without shutting down the entire pipeline, work? If not, why? Thanks in advance! Alessandro ---

Have a look here: [https://www.elastic.co/support/matrix](https://www.elastic.co/support/matrix) in the tab product compatibility Are you using some plugins that are not included in the 7.1? Are you using custom mappings/query templates etc? ---

Hi, thanks for you answer. I might have misspoken. I know that Beats and so on, can still send data to logstash even if logstash is at a newer version (e.g. Beats 6.8.x and LS 7.x), thus to give flexibility while scheduling the upgrades. What i wanted to know is that logstash can be upgraded WITHOUT shutting down the whole pipeline, as specified in [the docs (step 1)](https://www.elastic.co/guide/en/logstash/current/upgrading-using-package-managers.html), if the "service" is balanced with a load balancer. Is it really necessary to shut down the entire pipeline? I hope that i've been clearer now Many thanks, Alessandro ---
