Upgrading Your Current System

この章で説明しているのは、既存の Fedora を現行最新リリースにアップグレードする方法です。主に2つの基本的な方法があります:

dnf system upgrade の使用による自動的なアップグレード

The preferred way to upgrade your system is an automatic upgrade using the dnf system upgrade utility. For information on performing an automatic upgrade, see Fedora Wiki DNF system upgrade.

Manual Reinstallation

You can upgrade to the latest version of Fedora manually instead of relying on dnf system upgrade. This involves booting the installer as if you were performing a clean installation, letting it detect your existing Fedora system, and overwriting the root partition while preserving data on other partitions and volumes. The same process can also be used to reinstall the system, if you need to. For detailed information, see Manual System Upgrade or Reinstallation.


Manual System Upgrade or Reinstallation

Unfortunately, we have not written this chapter yet, and there is no dedicated documentation about a manual reinstall on the Wiki, either. In the meantime before we fix this, you can try to start the installation normally (from a boot CD/DVD/USB), select manual partitioning in your installer, and reuse existing partitions instead of destroying them and creating new ones. The instructions at Manual Partitioning should in most cases be easy to adapt for this.
