When using Fleet to upgrade the Elastic Agent, Kibana and Elasticsearch needed to bu upgraded first, before the Agent Upgrade becomes available according to the docs. If I upgrade Kibana/Elasticsearch from 8.11.1 to 8.11.3, the only available Agent upgrade is to version 8.11.2 instead it should be 8.11.3 right? I appreciate any advice. Thank you ---

Hi @stephenb unfortunately the provided link does not work. ---

I found the mentioned site, but unfortunately the workaround does not work, because thh Upgrade Agent button is greyed out (Kibana is running 8.11.4; Agents are running 8.11.3). I assume, that this issue is fixed, when upgrading to the next minor version 8.12.0 ---

You can use the API to request a bulk upgrade as described in the same documenttion. For example: ```auto POST kbn:/api/fleet/agents/bulk_upgrade { "agents": "fleet-agents.policy_id:uuid1-uuid2-uuid3-uuid4 and fleet-agents.agent.version<8.11.4", "version": "8.11.4" } ``` ---

This doesn't quite work, as Kibana wants me to upgrade fleetserver first. If i use a filter criteria fro fleetserver, the error says it cannot upgrade due to not upgraded fleetserver. ---

Agent version cannot be ahead of fleet version as far as I know. Yes if you want to run agent 8.11.4 you need fleet at that same release. ---

> [@Alphayeeeet](#): > > This doesn't quite work, as Kibana wants me to upgrade fleetserver first. What is your fleet server? You should keep it in the same version as Kibana. You may need to upgrade it using the command line as well using `elastic-agent upgrade 8.11.4` on your server. ---

I know I can upgrade using command line, but I will wait until we're upgrading to Elastic 8.12.x. The issue should then be fixed, I think. ---
