If your Launcher is installed from the Managed Play Store, you are already using the correct package name. If you downloaded Launcher from the BFE Portal, you are most likely using the old **`com.bluefletch.launcher`** namespace. In this scenario, refer to the [Upgrading to L4](#upgrading-to-launcher-4) section for more information. ## Configuration Changes You should be able to use your current Launcher 3 configuration with the new Launcher 4. Some newer features may require using the new app configuration section, but you can make those changes after you've upgraded the Launcher application. ## Upgrading to Launcher 4 Migrating from Launcher 3 to Launcher 4 equips your devices with the latest feature enhancements, new functionalities and improved performance. Launcher 4 also aligns strongly with Google Play app policies and requirements requiring a namespace change for customers that use the sideload version of the APK. Because of this, BlueFletch has provided both manual and automated procedures to ensure a smooth upgrade from Launcher 3 to Launcher 4.
