Upgrade a cluster

WCD does not automatically upgrade existing clusters when a new version of Weaviate core is released.

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

Check the server version​

Check for a Weaviate server update.

Upgrade the server version​

WCD restarts your cluster during an upgrade. A standard cluster is unavailable during the upgrade.

To avoid downtime, consider using high availability (HA) clusters for production workloads. An HA cluster upgrades one node at a time so the cluster is available during the upgrade.

To upgrade a cluster, follow these steps:

  1. Click the "Upgrade!" button on the cluster details tile.
  2. Enter your cluster name in the text entry box.
  3. Click confirm.

WCD Upgrade confirmation

During the upgrade, the console displays a status indicator.
