Upgrading directly from one release to the next using {{command|yum}} is not explicitly tested by Fedora QA and issues with them are not considered blockers for a release, but in practise works for many users due to our packaging guidelines providing detailed information on maintaining upgradability.  To learn more, refer to [[Upgrading Fedora using yum]].

* 执行升级前备份你的系统是个好主意。保持{{filename|/home}}在一个单独的逻辑卷或分区使备份用户数据更容易。这是一个要求Fedora安装程序支持的功能。 对这个问题的更多，请参阅[https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=150670 Bug 150670]。自Fedora13起这是默认的。
* It's a good idea to have a backup of your system before performing an upgrade. Keeping {{filename|/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 [https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=150670 Bug 150670] for more on this issue. This is the default from Fedora 13 onwards.


* 做一个干净的安装，然后从备份还原用户数据可能会对某些用户更好地工作。未来的发行可能会包含在这个过程中协助的特性。对于更多信息，请参阅[[Anaconda/WorkItems#upgrade|  AnacondaWorkItems]]。
* 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 [[Anaconda/WorkItems#upgrade|  AnacondaWorkItems]] for more information.


* 你可以使用标准安装DVD升级。Live媒体只执行全新安装而不升级。安装将覆盖默认安装设置冲突的任何第三方软件包。Fedora库内的应用程序都可轻松升级。对于更多信息，请参阅[http://docs.fedoraproject.org/install-guide/f{{FedoraVersion}}/ 安装指南]。
* 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 [http://docs.fedoraproject.org/en-US/Fedora/{{FedoraVersionNumber}}/html/Installation_Guide/index.html Installation Guide] for more information.


* 确保你在尝试升级之前仔细阅读[http://docs.fedoraproject.org/release-notes/f{{FedoraVersion}}/ 发行注记]。
* Make sure you read the [http://docs.fedoraproject.org/en-US/Fedora/{{FedoraVersionNumber}}/html/Release_Notes/ Release Notes] carefully before attempting an upgrade.

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

The process of using Anaconda installer to upgrade is the recommended and supported method and detailed in the Fedora Installation Guide. The Release Notes also have some useful information.

PreUpgrade

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.

直接通过Yum升级

Upgrading directly from one release to the next using yum is not explicitly tested by Fedora QA and issues with them are not considered blockers for a release, but in practise works for many users due to our packaging guidelines providing detailed information on maintaining upgradability. To learn more, refer to Upgrading Fedora using yum.

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)

If you are using a pre-release of Fedora, and want to know more about upgrading to the final release, refer to Upgrading from pre-release to final.

小技巧

  • 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.
