NVIDIA TensorRT Migration Guide

This guide covers the API and tooling changes required to migrate NVIDIA TensorRT workloads on NVIDIA DriveOS 6.x and 7.x. It addresses two migration paths: TensorRT 10.x to 11.x (primary) and TensorRT 8.x to 10.x (appendix).

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

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