Update a cluster

Weaviate Cloud (WCD) does not automatically update existing clusters when a new version of Weaviate core is released.

If you have a stand-alone cluster, an update requires system downtime. Consider your business needs, and update your cluster when you have a suitable maintenance window. There is no downtime if you have high availability (HA) enabled on your cluster.

Update the Weaviate Database version

When a Weaviate Database version update is available, a notification banner appears at the top of your cluster details page. The banner color and urgency depend on the update deadline:

• Info (Green background): Standard update notification
• Warning (Yellow/Orange background): Update deadline approaching
• Critical (Red background): Update deadline is imminent

Steps to update a cluster

To update a cluster, follow these steps:

1. Open the Weaviate Cloud console and select your cluster.
2. If an update is available, you'll see a notification banner at the top of the cluster details page. Click the Update button in the banner.
3. Select a Weaviate version for the update.
4. Enter the cluster name to confirm the update.
5. Click the Confirm and update button to start the update process.

Update process and status

During the update, the Update button becomes disabled and displays a loading indicator with descriptive text based on the current status:

• Preparing: The cluster is being prepared for update (may be unhealthy, being created, restarted, or expanding disk)
• Updating: The cluster is undergoing update operations or the version is being updated
• Backup in Progress: A data backup is currently in progress

The console displays status indicators throughout the process. The indicators disappear and Weaviate Cloud sends a confirmation email when the cluster is ready.

Important notes about the update process

• A complete backup of your data will be created before the Weaviate database version is updated
• The total duration of this process depends on the amount of data in your cluster
• For clusters with large volumes of data, the total duration to update may be lengthy
• Status indicators may not appear in a specific order, as they reflect real-time provisioning status
