# Update
This guide explains how to safely update your PanelAlpha installation.
# Before You Start
- Create a recent server backup or snapshot.
- Make sure you have root SSH access.
- Plan a short maintenance window (some panel functions can be briefly unavailable during update).

ssh root@your-server-ipRun the following command to start the update:
wget -N -P /opt/panelalpha https://license.panelalpha.com/single-server-installer.sh && bash /opt/panelalpha/single-server-installer.sh
The script auto-detects the existing installation, downloads the required bundle, and performs the update with no extra flags. No manual downloads or license key arguments are required.
