使用DVD升级

最好的升级方式
强烈推荐通过本方法升级您的Fedora系统到最新版

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 是一个可以让您继续使用Fedora的升级程序。 PreUpgrade 程序下载需要更新的软件包，一旦所有文件准备就绪，您将会收到提示重启以便开始跨版本升级的提示。本方法已经被Fedora官方明确支持，具体信息请参阅专门为其开设的页面：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。

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.

Rawhide版本是一个每天更新的滚动版。在正式发布之前，针对Fedora开发或者测试的相关人员均使用这个版本。
