Migrate from Bitnami subcharts
Camunda 8.9 is the last version that ships Bitnami subcharts. Starting with Camunda 8.10 (Helm chart 15.x), the bundled Bitnami subcharts (PostgreSQL, Elasticsearch, and Keycloak) are removed from the Camunda Helm chart.
If you run Camunda 8.9 (or earlier) with Bitnami subcharts and want to migrate to Kubernetes operators or managed services, follow the migration guide in the 8.9 documentation.
New Camunda 8.10 installations should provision operator-based infrastructure or managed services directly, without Bitnami subcharts.
Why is this guide only available for 8.9?
The migration tooling deploys a Bitnami-based "source" installation and migrates its data to operator- or managed-service-backed targets. Because chart 15.x (Camunda 8.10) no longer bundles Bitnami subcharts, the source side of the migration can only exist on Camunda 8.9 and earlier.
The recommended path is therefore:
- While on Camunda 8.9, migrate your Bitnami-managed infrastructure to Kubernetes operators or managed services.
- Then upgrade from 8.9 to 8.10 with a standard Helm upgrade, since your infrastructure is already operator- or managed-service-backed.
