Hello As I have seen a new version available I decided to upgrade Elasticsearch server OK ✅ Logstas server OK ✅ Elasticsearch server OK ✅ kibana server OK ✅ Fleet server [don't know] 🫤 I understand that the fleet server is an agent that takes the role of coordinator or administrator of the other agents. Should I just stop the service with a **systemctl stop elastic-agent** and then do an **apt-get update && apt-get install elastic-agent**? ![image](https://us1.discourse-cdn.com/elastic/original/3X/4/b/4b2175f0d752f0d27aea4c539e5b8d0ab13293a9.png) ---

As the agent that is in the fleet server acts as the administrator or coordinator of the other agents, it must be updated in a different way. I did it with the command `sudo elastic-agent upgrade 8.15.3` > **[Upgrade standalone Elastic Agents | Fleet and Elastic Agent Guide \[8.15\] |...](https://www.elastic.co/guide/en/fleet/current/upgrade-standalone.html)** ![image](https://us1.discourse-cdn.com/elastic/original/3X/f/d/fd8da62f00233b31750ff986b84df15909c15036.png)
