i, someone can help me with migration from redhat 4 to centos 4 with a dell poweredge machine in RAID 5. i have sequence from old mailist than can migration from redhat 3 yo centos 3 with the next sequence, from Ted Targosz: #### we performed the following steps to migrate a RHEL 3.0 machine to centos 3.7

backup all data

Import GPG Keys: rpm --import http://mirror.centos.org/centos/3.7/os/i386/RPM-GPG-KEY-CentOS-3

Install yum: rpm -Uvh --nodeps http://mirror.centos.org/centos/3.7/os/i386/RedHat/RPMS/yum-2.0.8-1.centos.7... http://mirror.centos.org/centos/3.7/os/i386/RedHat/RPMS/centos-yumconf-1-11.... http://mirror.centos.org/centos/3.7/os/i386/RedHat/RPMS/centos-yumcache-3.1-...

Update Release information: rpm -e redhat-release-3ES-13.6.2 && rpm -ivh http://mirror.centos.org/centos/3.7/os/i386/RedHat/RPMS/centos-release-3-7.1...

then just: yum upgrade

and voila, after all downloaded and installed (and a reboot because of kernel upgrade)...we were running on Centos 3.7 (and getting free updates/patches) ####

question: i can do the same procedure with redhat 4 to centos 4 ?? i read a lot, lot lot info doc, and i try my own move, like: #linux update #linux upgradeany ..etc..the result is kernel panic... that all.. i hope some help. Thanks
