Upgrade Continuous Delivery for PE

Check for, download, and deploy updates from the Version history tab in the platform admin console. These instructions apply to installations in online environments.

In the platform admin console, click Version history.
Click Check for updates.
Configure an automatic update check by clicking Configure automatic updates. You can check for updates hourly, every four hours, daily, weekly, or at a custom interval.
If an update is available, the platform admin console downloads it for you and performs preflight checks on your system to make sure your cluster meets system requirements for the new version. Review the outcome of these checks by clicking View preflight.
When you're ready to upgrade to the new version of Continuous Delivery for PE, click Deploy.

Upgrade the platform admin console

Upgrade the platform admin console to take advantage of new features and bug fixes, and to upgrade your cluster to the latest version of Kubernetes when one is available.

On your control plane node, rerun the installation script, passing in any arguments you included when installing for the first time:
```
curl -sSL https://pup.pt/install-cd4pe | sudo bash
```
If a new version of Kubernetes is available, the system will provide upgrade scripts to run on each node in your cluster.

Note: During the Kubernetes upgrade process, nodes are not able to properly route network connections. Make sure you have load balancers or a multi-node failover process in place, or schedule downtime before upgrading.
