Migration Guide#

This guide covers the API and tooling changes required to migrate NVIDIA TensorRT workloads. The primary path is TensorRT 10.x to 11.x; an appendix covers TensorRT 8.x to 10.x. Platform-specific pages for NVIDIA DriveOS and Jetson/JetPack address deployment-target differences where they affect migration steps.

If you are unfamiliar with these changes, refer to the TensorRT sample code for clarification.

Choose Your Migration Path#

Use the tables below to pick the page that matches your starting version, deployment target, and integration surface. Each linked page includes paired before/after examples where applicable.

Migrating from TensorRT 10.x to 11.x (primary path)

If you…	Start here
Need the full 10.x -> 11.x overview (strong typing, plugin V3, removed APIs)	Migrating from TensorRT 10.x to 11.x
Ship a Python application or build script	Python API migration
Ship a C++ application	C++ API migration
Use trtexec or other CLI build/inference workflows	trtexec migration
Use the Safety Runtime (ISO 26262 automotive)	Safety Runtime migration
Depend on IEngineInspector for engine introspection	IEngineInspector migration
Deploy on NVIDIA DriveOS	DriveOS migration
Maintain a Jetson / JetPack deployment	TensorRT 11.4.1 supports NVIDIA JetPack 7.2.2 or later on Jetson AGX Orin and Jetson Thor, installed from the Linux SBSA package. Refer to Jetson migration. On NVIDIA JetPack 6.x, remain on a TensorRT 10.x release supported by the installed JetPack version.

Migrating from TensorRT 8.x to 10.x (appendix)

If you…	Start here
Are still on 8.x and upgrading to 10.x first	Appendix overview
Need Python API deltas for 8.x -> 10.x	Python API migration
Need C++ API deltas for 8.x -> 10.x	C++ API migration
Need trtexec changes for 8.x -> 10.x	trtexec migration
Need Safety Runtime changes for 8.x -> 10.x	Safety Runtime migration
