Upgrade the Control Tower

Using Helm (directly)

To upgrade to the latest version using Helm, run:

helm repo add flightcrew https://flightcrew-helm-charts.storage.googleapis.com/control-tower/stable
helm repo update
# --reuse-values ensures that any custom values from the previous installation are retained during the upgrade.
helm upgrade control-tower flightcrew/control-tower --namespace flightcrew --reuse-values

Using Helm (via Terraform)

To upgrade using Terraform, run:

terraform plan
terraform apply

Terraform will automatically fetch and apply the latest available chart version from the repository. Make sure the version field is omitted in your Terraform configuration.
