> ⚠️ **Legacy documentation (cBioPortal v6 and earlier).** This page predates cBioPortal v7, which replaced MySQL with ClickHouse and made Docker Compose the only officially supported deployment method. It is retained for historical reference only — do not rely on it for a v7 deployment. See the [current deployment documentation](/deployment/README.md) and the [v6-to-v7 migration guide](/Migration-v6-to-v7.md).

This file has been deprecated and information about customizing cBioPortal can be found in [application.properties documentation](/deployment/customization/application.properties-Reference.md).
