+Using this command is a recommended way of upgrading relatively simple React Native apps with not too many native libraries linked. The more iOS and Android build files are modified, the higher chance for a conflicts. The command will guide you on how to continue upgrade process manually in case of failure.

+_Note: If you'd like to upgrade using this method from React Native version lower than 0.59.0, you may use a standalone version of this CLI: `npx @react-native-community/cli upgrade`._
