I haven't experienced any problems using this method: su <root passwd> yum update (hit YES when prompted) (go out for a cup of coffee while it downloads and updates) /sbin/shutdown -r now (system wakes up as CentOS 4.3 box) It's THAT easy. These were all rather vanilla systems without any special drivers or custom kernels that were just doing standard DNS/mail/web services and it just plain worked. The CentOS team did a great job!
