# Qualcomm Linux 2.0 migration overview

This guide provides a high-level overview of migration from Qualcomm^®^ Linux^®^ 1.0 to Qualcomm Linux 2.0. It outlines the major areas that the migration impacts, which include the following:

- Changes to the build system
- Qualcomm-authored OpenEmbedded layers
- Kernel and image recipes
- Machine configurations
- BitBake override usage
- Qualcomm Linux technology features

Additionally, it describes over-the-air (OTA) upgrade considerations and highlights key platform and feature-level changes that you must consider when upgrading to Qualcomm Linux 2.0.

Note

Qualcomm Linux 2.0 supports the long-term support (LTS) kernel v6.18 release.

This guide also describes how you can use modular Qualcomm value-added components as overlays. For more information on Qualcomm Linux overlays, see [Enable and evaluate Qualcomm Linux overlays](https://docs.qualcomm.com/doc/80-80021-150/topic/overlay_overview.html#overlay-overview).
