Hi All,

I’ve a question on upgrading Centos with the least downtime…

I’ve a centos 4.6 machine, hosting my local Centos respository. I’d like to upgrade the OS to 5.1

I’ve practised in a VMware machine upgrading it by booting from a CD, but I wondered if YUM could do it, whilst keeping the rest of the machine “alive”.

Am I better to shutdown and upgrade, or is yum really *that* good?

I believe the 4.x -> 5.x path via yum is doable but actually tends to be a bit of work (I think I recall a rather detailed forum post describing the procedure).

I think the anaconda (from CD) method would probably be your smoothest option.
