i have upgraded my elastic cloud from 7.x to 8.9.1 so, i have to upgrade the filebeat, logstash, metricbeats and heartbeat.
this beats are running on "red hat enterprise linux" and this are the current beats version like that.
filebeat => 6.8.3
logstash => 7.17.11
metricbeat => 6.8.3
heartbeat => 6.8.3
so, can you explain me in which flow how can i upgrade the beats like filebeat 1st or logstash 1st. and can you give me the steps regarding beats upgradation so, i will go through that.
Note:- i have refer the docs but little bit i am getting confuse so, what does mean breaking changes and how to apply the breaking changes.
