# SDK Upgrade Guide

### **General Information**

Before you proceed with the upgrade, here are some essential points to keep in mind:

1. **Backup Your Project**: Before making any changes, it is crucial to back up your Unity project to avoid any potential data loss or issues during the upgrade process.
2. **Version Compatibility**: Ensure that the version of Unity you are using is compatible with ARway. Check the [Getting Started](https://docs.arway.ai/arway-sdk/getting-started) page for more information about supported versions of Unity.
3. **Asset Compatibility**: If your project relies on third-party assets that interact with ARway, make sure those assets are also compatible with the new version.
4. **Test Thoroughly**: After the upgrade, thoroughly test your project's functionality to identify and fix any issues that may have arisen during the transition.
