+> If you need CUDA 13, use our [ComfyUI CUDA 13 template](https://console.runpod.io/hub/template/comfyui-cuda-13?id=2lv7ev3wfp) instead.
+
+## Upgrading from a previous version
+
+If you have an existing pod created with an older version of this template (CUDA 12.4), a one-time migration of the virtual environment will be performed automatically on the next boot to make it compatible with CUDA 12.8. This may take a few extra minutes on first start after the update.

-Run the latest ComfyUI optimized for NVIDIA Blackwell architecture (RTX 5090, B200). First start installs dependencies (takes a few minutes), then when you see this in the logs, ComfyUI is ready to be used: `[ComfyUI-Manager] All startup tasks have been completed.`
