Dedoimedo posted a quick tutorial about upgrading CentOS 6.0 to 6.1

First, there's gonna be a 6.2 upgrade article, too, so relax. Now, normally, I never upgrade Linux versions from within a running operating system using the package manager. My experience shows that this procedure is usually rift with bugs and problems, ending in a system that is not suitable for production use. Which makes my decision to attempt just that with CentOS all the more intriguing.

But CentOS is a pillar of stability, a recent addition to my desktop arsenal. Long awaited and long supported, it is simple, light and fast. Moreover, there are no problems and issues that usually plague most of the competition. Hence, the silver medal in the 2011 best distro competition. Now, the only thing I have never checked is how well it copes with an upgrade. Now that CentOS 6.1 is out, this is the perfect opportunity to check that. In a way, this is a mini-review if you will, but mostly the tale of my upgrade.
