Online Upgrade from CentOS-4/Final

The best way to move from CentOS-4 to CentOS-5 is via an installer
upgrade. However if you must do it online, here are some tips to help:
- Remove as many packages as you can, strip it right back to the
original OS if possible
- Backup everything
- Disable all repositories, except the centos-5 OS and Updates repos
- init 3
- shutdown as many services as possible
- download and install the centos-release-5.x rpm, which will update
your yum configs
- run a yum upgade ( not update )

注：升级有危险，备份好重要内容
