Server version

Weaviate Cloud (WCD) hosts clusters that run Weaviate.

New clusters​

When you provision a new cluster, Weaviate Cloud uses the latest available version of Weaviate to set up the new cluster.

Updates​

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

The Weaviate Cloud console informs you when a newer version is available. Consider your business needs, and update your cluster when you have a suitable maintenance window.

Cluster downtime

Weaviate introduces Raft, an improved cluster synchronization mechanism, in v1.25. There is some downtime when you upgrade an HA cluster to 1.25 while the cluster switches to the new mechanism.

Security updates​

Weaviate Cloud does not automatically update clusters, however if an existing cluster has a security vulnerability, Weaviate Cloud updates the cluster when a fix is released.

For security updates, Weaviate Cloud updates the cluster to the most current production release unless there are known compatibility issues. If there are compatibility issues, the cluster is updated to the most recent compatible version.

Additional considerations​

  • Billing: If your cluster's Weaviate version cannot support the billing requirements for your pricing plan, Weaviate Cloud updates your cluster to the current production version or the most recent compatible version.
  • Data integrity: If your cluster's Weaviate version has a known risk of data loss or corruption, Weaviate Cloud updates the cluster when a fix is released.
  • Downgrade: You cannot downgrade your cluster to an earlier version of Weaviate.
  • Enterprise cloud customers: If you are an enterprise customer and you require a specific version of Weaviate, contact your support representative. In some circumstances, Weaviate Cloud can install a specific Weaviate version.
