# Upgrading
Upgrading an air-gap environment can be accomplished in the following manner:
1. Download the new air-gap images (tar file) from the [releases](https://github.com/rancher/k3s/releases) page for the version of K3s you will be upgrading to. Place the tar in the `/var/lib/rancher/k3s/agent/images/` directory on each node. Delete the old tar file.
