Hello, I'm trying to take a box from 4.4 to 5.0 and doing it via binary yum upgrade. I'm following the procedure at: http://lists.centos.org/pipermail/centos-announce/2007-April/013660.html for taking a 4.x box to 5. I've removed any unneeded rpms, and confirmed the state of the system. I downloaded and installed centos-notes-5 and ran an rpm -Uvh centos-release-5 which worked. I imported the centos 5 gpg key and confirmed the status of my yum. Then i ran: yum upgade this didn't work, yum didn't recognize that as a valid option. Is that a mistype? Or is there another step i have to do? Thanks. Dave.
