On AWS, the Braintrust data plane runs on Lambda and EC2. The data plane version is bundled into the Terraform module — each module release pins specific versions of the Braintrust API and Brainstore in VERSIONS.json. When you update your module source to a newer version and run terraform apply, Terraform automatically deploys the corresponding data plane.To check which data plane version you’re currently running, go to Settings > Data plane in the Braintrust UI.
Check the Self-hosting releases page for your target data plane version to find the minimum Terraform module version required. Then update the ?ref= in your module source:
Carefully review the output of terraform plan before applying. If you see something unexpected, like deletion of a database or S3 bucket, contact Braintrust for help.
Apply the changes:
terraform apply
This updates both the infrastructure and the data plane components in a single apply.
This guide shows the routine process for upgrading the Braintrust data plane in your GCP account.
GCP deployments have two independently upgradeable components:
Terraform module (terraform-google-braintrust-data-plane): provisions your cloud infrastructure — the GKE cluster, Cloud SQL database, Redis, and storage buckets. You upgrade this by changing the ?ref= version in your module source and running terraform apply.
Helm chart: deploys the Braintrust application (API and Brainstore containers) onto your GKE cluster. You upgrade this by running helm upgrade with a new --version.
The Helm chart --version is the chart version, not the data plane version. The data plane version is set separately via image tags in your values.yaml. Upgrading the Helm chart alone does not change which data plane version is running — you must also update the image tags.
To check which data plane version you’re currently running, go to Settings > Data plane in the Braintrust UI.
Before upgrading, check the Self-hosting releases page for your target data plane version. Each entry specifies its requirements:
“Requires: Helm X.Y.Z+” — you must upgrade the Helm chart to at least that version before or alongside updating your image tags. Update Terraform first if infrastructure changes are also listed.
No requirements listed — you can upgrade by updating image tags in values.yaml and running helm upgrade. No Terraform or chart version change needed.
Helm-only release (“No data plane version change”) — update only the Helm chart version. No image tag change needed.
Run this step when a release lists infrastructure requirements, or when you want to apply infrastructure changes independently.
terraform apply
Carefully review the output of terraform plan before applying any changes to your deployment. If you see something unexpected, like deletion of a database or storage bucket, contact Braintrust for help.
To pin to a specific Terraform module version, update the ?ref= in your module source:
Run this step to deploy a new data plane version or apply a Helm chart update.

Set the data plane version
Set the data plane version by updating the image tags for the API and Brainstore in your values.yaml. Refer to the Helm chart values reference for the exact field names.
Azure deployments have two independently upgradeable components:
Terraform module (terraform-azure-braintrust-data-plane): provisions your cloud infrastructure — the AKS cluster, Azure Database for PostgreSQL, Redis, and storage. You upgrade this by changing the ?ref= version in your module source and running terraform apply.
Helm chart: deploys the Braintrust application (API and Brainstore containers) onto your AKS cluster. You upgrade this by running helm upgrade with a new --version.
