Migrating from JetPack 6.x to JetPack 7.2
This page is for existing JetPack 6.x users on the AGX Orin Developer Kit. New kits: start with Quick Start instead.
What changes
| Layer | JetPack 6.x era | JetPack 7.2.1 |
|---|---|---|
| Jetson Linux (L4T) | 36.x (6.2 used 36.4.x) | 39.2.1 |
| OS / root filesystem | Ubuntu 22.04 | Ubuntu 24.04 |
| Linux kernel | 5.15 | 6.8 |
| CUDA | 12.x | 13.2.2 |
| TensorRT | 10.x (6.x era) | 10.16.2 |
Values for the JetPack 6.x column are illustrative (JetPack 6.2 era). Check your exact current versions with
cat /etc/nv_tegra_releasebefore planning, and see NVIDIA's JetPack Archive for per-release details.
What's new for Orin in the 7.2 line
From the Jetson Linux 39.2 release notes:
- The Jetson Orin family joins the JetPack 7 software line (same generation as Thor).
- Unified ISO installation — a USB-stick install path, no host PC required.
- NemoClaw single-command installation for agentic AI workflows.
- Official Yocto/OpenEmbedded recipes (OE4T) for custom production images.
- Camera stack: SIPL API v2.0 (GMSL and CoE) — note this release has ABI changes: UDDF drivers built for JetPack 7.1 must be rebuilt against JetPack 7.2 headers.
- (AGX Orin 32GB Super Mode / MAXN_SUPER is 32GB-specific and does not apply to the 64GB kit. SBSA and MIG changes relate to Jetson Thor.)
What cannot be carried over — plan to rebuild
- Out-of-tree kernel modules — kernel moved to 6.8; modules must be rebuilt against the new headers.
- Camera drivers and device-tree customizations — rebuild for 39.2; SIPL 2.0 also brings ABI changes for UDDF drivers.
- TensorRT engines — serialized engines are tied to the TensorRT version; rebuild with TensorRT 10.16.2 on target.
- CUDA binaries — rebuild with CUDA 13; do not expect 12.x binaries to carry over.
- Containers — switch to JetPack 7-compatible images (e.g., updated NGC containers).
- Python environments and system services — recreate for Ubuntu 24.04 (package names, repositories, and interpreter versions moved).
Recommended migration order
- Confirm your software stack is supported on 7.2.1 before wiping anything — check each component you depend on against NVIDIA's JetPack 7.2.1 component list. That page can lag for independently released SDKs: it still lists Isaac ROS as "coming soon" although Isaac ROS 4.6.0 added Jetson Orin + JetPack 7.2 support (see Robotics on JetPack 7.2).
- Back up: application data, sensor calibration files, container volumes, device-tree sources, TensorRT build scripts/ONNX models.
- Flash JetPack 7.2.1 (Flash & Updates) and validate: boot, storage, networking, and that Force Recovery still works.
- Restore peripherals: Wi-Fi, cameras, CAN, or fieldbus drivers — rebuilt for kernel 6.8.
- Rebuild CUDA applications, TensorRT plugins, and TensorRT engines on the target.
- Validate your application in its original power mode first; only then try other performance modes.
- Record baselines: memory use, thermals, power draw, latency, throughput — before moving to production.
Rollback
- Before wiping, keep a known-good copy of your current system (a spare NVMe/eMMC image, or at minimum the data from step 2).
- The ISO installer can install any L4T version for which you hold media — keep the older installer USB if you may need to go back.
- For fleets: stage the rollout, and prefer designs with an independent recovery path (recovery USB + backup image) over in-place upgrades.

Status: draft, pending review by cheny. Grounded in NVIDIA's official documentation as of the date listed; not yet verified on physical hardware by Juxi Technology. The rebuild list describes standard platform consequences (kernel/TensorRT/CUDA version changes) — validate against your own stack.
