We have been in the process of upgrading our elastic agents from 7.13.0 to 7.15.1. Currently we have been able to upgrade the agents individually via the GUI however we are not able to perform a bulk upgrade of all the agents as there is no way to select all the hosts within our Kibana.
On the Elastic Documentation it does say it can be done:
But when we compare it to what we can see on our Kibana we do not get the option to select multiple hosts:
We have tried both Kibana v8 and v7 but the checkboxes to select multiple hosts doesn't appear. Is there a configuration option that we are missing. We are looking to roll the agent out to a larger set of hosts so any help would be much appreciated.
Thanks in Advance.
