使用Anaconda安装器来跨版本升级是官方推荐的方法,具体请见:Fedora安装手册当前正式版本详情 也有很多有价值的信息。


PreUpgrade is an application you can use to upgrade Fedora while continuing to use it. PreUpgrade downloads the packages required for the upgrade. Once everything is downloaded and set up, you will be notified that you can reboot at any time to start the Fedora upgrade. This method of upgrading is explicitly tested and supported by Fedora. To read more, refer to PreUpgrade.


通过Yum来跨版本升级也是个不错的方法,但是本方法尚未被Fedora QA小组明确测试通过。本方法也许不会导致升级失败。由于打包指南在升级维护方面提供了很详细的信息,绝大多数用户可以尝试。具体信息位于: 用Yum升级Fedora指南

从一个不稳定的发行版升级到稳定版(比如alpha, beta, release candidate版本或者其他开发版本)

如果您正在使用不稳定版本的Fedora,并向升级至稳定版,请按照这个指南:非正式版本升级到正式版指南 来完成。


  • It's a good idea to have a backup of your system before performing an upgrade. Keeping /home in a separate logical volume or partition makes backing up user data easier. This is a feature requested for the Fedora Installer. Refer to Bug 150670 for more on this issue. This is the default from Fedora 13 onwards.
  • Doing a clean installation and then restoring user data from backups may work better for some users. Future releases may include features to assist in this process. Refer to AnacondaWorkItems for more information.
  • You can do an upgrade using the regular installation DVDs. Live media only performs fresh installations, not upgrades. The installation overrides any third party packages which conflict with the default installation set. Applications within the Fedora repository are easily upgradeable. Refer to the Installation Guide for more information.
  • Make sure you read the Release Notes carefully before attempting an upgrade.
