What we've done a good bit of, to upgrade one server from another that's already where we want it to be, is this: 1. On the target machine, mkdir /new /boot/new 2. rsync -HPavx <sourceserver>:/boot/. /boot/new/ 3. rsync -HPavx -exclude=/old -exclude=/var/log/wtmp <sourceserver>:/. /new/ (exclude anything else you want) 4. Copy /etc/fstab, /etc/sysconfig/network, /etc/sysconfig/network-scripts/ifcfg-e*, /boot/grub/device.map, and /etc/exports, if any, to /boot...

I have older systems out there that work fine, just for what ever reason would be great to upgrade from a C5 -> C7 (due to no longer supported) or C6 > C7 (for updated packages). Sounds like the upgrade tool is not quite an option... I was thinking...

Hello all... I have a remote machine running C6. I desire to update it to C7. Not possible to be on-site. Can I copy the Everything ISO for C7 to the machine, mount -o loop C7.Everything.iso /media/cdrom then do a "yum upgrade" ? Will that work? The server is using software raid. Thanks Jerry

My questions 1- what is the easiest way to do this? 2- do I need to partition hard-drive of new server exactly as old one? 3- Is there any changes to make on new server after full migration? 4-
