### Prerequisites

* **User permissions**: Users must have the [Agent Upgrade][2] permission within Fleet Automation. The permission is enabled by default on the Datadog Admin role.
* **Disk space**: Datadog suggests at least 2GB for the initial Agent install and an additional 2GB for upgrading the Agent from Fleet Automation. Specifically, the upgrade requires 1.3GB in the `/opt/datadog-packages` directory. The extra space ensures that there is enough room to maintain two Agent installs temporarily during the upgrade process in case a rollback is needed.

### Upgrade your Agents

Similar to a manual upgrade, expect a downtime of 5-30 seconds while the Agent restarts. The full upgrade process takes approximately 5 minutes. Around 2 minutes of this time is used for the upgrade process. The rest of the time is spent monitoring the upgrade to ensure stability and determining if a rollback is necessary. If the upgrade fails and a rollback is necessary, the Agent automatically reverts to the previously running Agent version.

The upgrade process primarily adds files to the following directories:

Linux and macOS:
* `/opt/datadog-packages`
* `/etc/datadog-agent`
* `/etc/systemd/system`

Windows:
* `C:\ProgramData\Datadog Installer\packages`
* `C:\Program Files\Datadog\Datadog Agent`

The Agent ensures that the appropriate permissions are set for these files. No configuration files are altered during the installation process.
