Redhat 4から5へのアップグレード

DVDで普通に起動しただけではアップグレードの選択肢が出てこなかった。



ググった結果、DVD起動時にlinux upgradeanyとして指定すればよいとのこと。なんとか成功した。

  If the contents of your /etc/redhat-release file have been changed from the default, your Red Hat Enterprise Linux installation may not be found when attempting an upgrade to Red Hat Enterprise Linux 5.2.



  You can relax some of the checks against this file by booting with the following boot command:



  linux upgradeany



  Use the linux upgradeany command if your Red Hat Enterprise Linux installation was not given as an option to upgrade.
