yum直接从一个版本升级到下一个。它不是官方支持方法，但是对很多用户可行。了解更多，请参阅Upgrading Fedora using yum。
如果你正在使用Fedora预发布版，并想了解关于升级到正式发布的更多，请参阅Upgrading from pre-release to final.
- It's a good idea to have a backup of your system before performing an upgrade. Keeping
/homein 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.
