Hello BRAIN,
First of all, could you kindly confirm if your trial period is over or not? If over then anashetty and Venkat V have shared the correct findings with you.
To directly address your question — "Is there a way to renew or extend the NVIDIA AI Enterprise subscription on my existing VM without recreating it?" — the answer is:
No, it is not possible to extend the NVIDIA AI Enterprise trial beyond the allowed 15 + 15 days on the same VM.
This limitation is by design. The entitlement metadata that activates the NVIDIA AI Enterprise subscription is tied to the original VM deployment. Even if you generate new API keys or activation tokens, the backend system recognizes the VM as expired and will not allow further renewals or activations on that instance.
What to do now?
To continue using NVIDIA AI Enterprise services and preserve your existing environment, purchase the paid version of NVIDIA AI Enterprise. Make sure to select the plan that matches the number of GPUs in your VM (e.g. "1 GPU Plan" for a 1-GPU VM).
Your next concern is you want to preserve your data on that VM so before you recreate or redeploy your VM using the paid image, you can preserve your current setup by capturing the image of your VM and then redeploy a new VM using the paid image, and restore your environment from the captured image or by reattaching your disk and migrate software and data using tools like scp, rsync, or azure backup.
Hope this answers your query. Let me know if you have any further query. Thanks.
