Upgrade Fleet-managed Elastic Agents
editUpgrade Fleet-managed Elastic Agents
editWant to upgrade a standalone agent instead? See Upgrade standalone Elastic Agents.
With Fleet upgrade capabilities, you can view and select agents that are out of date, and trigger selected agents to download, install, and run the new version. You can trigger upgrades to happen immediately, or specify a maintenance window during which the upgrades will occur. If your Elastic Stack subscription level supports it, you can schedule upgrades to occur at a specific date and time.
This approach simplifies the process of keeping your agents up to date. It also saves you time because you don’t need third-party tools or processes to manage upgrades.
Elastic Agents require internet access to perform binary upgrades from Fleet.
The upgrade feature is not supported for upgrading DEB/RPM packages or Docker images.
To upgrade your Elastic Agents, go to Management > Fleet > Agents in Kibana. You can perform the following upgrade-related actions:
| User action | Result |
|---|---|
Upgrade a single agent to a specific version. |
|
Do a rolling upgrade of multiple agents over a specific time period. |
|
Schedule an upgrade of one or more agents to begin at a specific time. |
|
View the status of an upgrade, including upgrade metrics and agent logs. |
|
Stop an in-progress upgrade. |
