Upgrade your hila deployment

In general, to upgrade your hila deployment, you simply perform a new install with the same procedure you used to perform the initial installation (see Install hila). However, you should check a few things to make sure your existing configuration and data are preserved during the update.

Tip: You should perform the upgrade in a staging area that is as close to the production environment as possible, to make sure the upgrade process works as expected before performing it in production.

Make sure the $data_dir env variable is set to the same location as in your existing installation. This ensures that your existing data is preserved.
All persistent data is stored in $data_dir, so you can copy and store all the files somewhere safe as a manual backup process.
The install script already handles fetching the existing passwords/secrets and reuses them for the upgrade, so no need for you to manage them.
You should have 500 MB of free disk space available for the upgrade process to complete successfully.
Back up your k8s/k3s directories.

Note: If you run the install script without setting $data_dir to a custom path, all the data is stored in the default directory used by k3s /var/lib/rancher/k3s. If you uninstall k3s, then the persistent data is removed as well.
