Important!

Upgrading Automation Suite enables maintenance mode on the cluster, which causes downtime for the entire upgrade duration.

Requirements

Important!

It is strongly recommended to create a backup of the cluster and the SQL database before upgrading Automation Suite. This is to ensure you can restore the cluster if something goes wrong during the upgrade operation.

Cluster data is backed up on NFS server. Make sure you have configured NFS server before proceeding further.

 

Overview

---

The following illustration shows the steps you need to take for a successful upgrade operation.

For a complete upgrade operation, follow these steps:

1. Configure a backup before upgrading the cluster to a new version, if possible.
2. Enable maintenance mode on the cluster, by bringing down the cluster network, to avoid any writes during upgrade. This step ensures the upgrade is consistent.
3. Upgrade Kubernetes and other infrastructure components on all the cluster nodes.
4. For offline installations, hydrate Private Docker Registry with the new container images.
5. Upgrade the fabric and shared components on the cluster.
6. Upgrade the services (UiPath products).
7. Bring back the cluster by disabling the maintenance mode on the cluster.
