upgrade Fedora 14 to Fedora 15

Since Fedora 15 was released for some time already, I upgraded my development server from Fedora 14 to Fedora 15 recently. Below is the command set I used to upgrade to Fedora 15. Before run those commands, I backup my virtual machine files in case.

# change account to Root account
[yyjia@jiaFedora14 ~]$ su

# upgrade to latest rpm version
[root@jiaFedora14 yyjia]# yum upgrade rpm
Loaded plugins: langpacks, presto, refresh-packagekit

Setting up Upgrade Process
No Packages marked for Update
[root@jiaFedora14 yyjia]# 

#make sure I have latest packages installed.
[root@jiaFedora14 yyjia]# yum -y update

#clean up yum cache.
[root@jiaFedora14 yyjia]# yum clean all

#insall preupgrade package.
[root@jiaFedora14 yyjia]# yum install preupgrade

#running preupgrade
[root@jiaFedora14 yyjia]# preupgrade

After running preupgrade, we have below screen. I don't want to try Fedora 16 beta version. So, I selected Fedora 15.

I followed instructions shown on the screen. Then, I have a below screen to ask for reboot.

After reboot, the upgrade process starts.


Here is upgrade manual from Fedora web site: http://fedoraproject.org/wiki/YumUpgradeFaq
