Upgrade a Weaviate cluster to a larger plan using the DigitalOcean API or Control Panel. Only upgrades are supported; you cannot downgrade to a smaller plan.

You can resize existing Weaviate clusters to a larger plan. Allowed upgrade paths are small to medium or large, and medium to large.

Resize a Cluster Using the API

To resize a Weaviate cluster, send a POST request to the resize endpoint with the target plan size:

curl -X POST "https://api.digitalocean.com/v2/vector-databases/$CLUSTER_ID/resize" \
  -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "size": "medium" }'

The cluster status moves out of active while the resize runs and returns to active when it completes. Connections may be briefly interrupted during the cutover.

Resize a Cluster Using the Control Panel

To resize a Weaviate cluster, go to the Vector Databases page in the Control Panel and select the cluster you want to resize. On the cluster’s Overview page, click the Settings tab. In the Configuration section, click Edit.

Select a larger plan. You can upgrade from Small to Medium or Large, or from Medium to Large. Downgrading is not supported.

Click Save to start the resize. The cluster status changes while the resize runs and returns to active when it completes.
