1 Introduction

The information presented here is applicable to any of the following scenarios:

Have hardware/software currently deployed on xWR6843 ES1.0 and want to migrate it to xWR6843 ES2.0
Have hardware/software currently deployed on xWR1642 and want to migrate it to xWR6843 ES2.0
Have hardware/software currently deployed on xWR1642 and want to migrate it to xWR1843
Have hardware/software currently deployed on xWR6843AOP ES1.0 and want to migrate to xWR6843AOP ES2.0

The information presented in this document covers:

Comparison of the base and the new target device along-with a description of how those differences impact existing hardware and software.
SDK version required for the new target device and updates needed in application build infrastructure (makefiles and/or CCS projects, linker command files, and so forth)
Updates needed in application source code, for example, API updates, new structure parameters, and so forth.
Example source code comparison snapshots are provided for easy reference.

For information specific to your current and target device, see the following sections.
