# Upgrading from version 12.x

If you have Enhance 11.x, please follow this guide instead.

If you have Enhance 12.0.0 or above, upgrading Enhance is easier than ever. As root, run:

apt update
apt upgrade

Do this on every server, starting with the control panel server.

If you see 404 errors from the MariaDB repository, you can fix this by running:

rm /var/lib/apt/lists/*mariadb*
apt update
apt upgrade
