An error occurs during a rolling upgrade of Data Collection Device (DCD) cluster" "Detected multi-zone environment with insufficient number of DCDs in a single zone"


You are unable to perform a rolling upgrade


-- 3 or more DCDs across all zones -- 2 or more DCDs in a single zone -- None of the DCDs are in the same zone as the Configuration Management (CM) device


Change the zone of the CM device from 'default' to one of the other zones. You can modify the option in the UI under System-> This Device -> General Properties -> Edit Impact of workaround: This will restart elasticsearch and potentially initiate a rediscovery of all shards if a new master is elected.
