To convert the node provider API to the new provisioner API, you need to follow these steps:

1. Set Cudo.PROVISIONER_VERSION = clouds.ProvisionerVersion.SKYPILOT in your clouds/cudo.py file.
2. Implement the sky/provision/cudo/* files as suggested in the documentation for adding new clouds.
3. If you already have your node provider implemented, it won't be difficult to convert it to the new provisioner API. You can refer to the runpod new provisioner implementation for guidance.
