Hello there!

I'd like to update my ELK stack to the 7.0 version.  
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 would 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
