# How do I modernize Drools applications from old versions (7.x)?

> Modernize legacy Drools 7.x applications by moving DMN, DRL, and BPMN assets onto the cloud-native Kogito runtime - without rewrites or re-certification.

Older Drools 7.x applications typically run on the legacy KIE Server / RHPAM
stack with monolithic deployments. The modern path is to move that logic onto the
cloud-native **Kogito** runtime — keeping your existing DMN, DRL, and BPMN assets
while gaining faster execution, smaller footprints, and container-native
deployment.

Aletyx is positioned as a **drop-in replacement** for aging Drools 7.x, jBPM,
RHPAM, and KIE Server deployments, so you can modernize **without rewrites,
behavior changes, or re-certification**. The recommended approach is to:

* Bring your existing rule and process assets into Aletyx as-is.
* Validate behavior with natural-language and regression testing.
* Deploy to cloud-native, multi-environment infrastructure.

See [docs.aletyx.ai](https://docs.aletyx.ai) for migration guidance.
