Agreed. It appears others have had success doing so; but, I prefer to
eliminate as many variables as possible.
I've done the following:
1. yum update Server 1.
2. complete a minimal CentOS install on Server 2. <<must be the same
version as Server 1>>
3. yum update Server 2.
4.Then boot both using LiveCD of choice.
<<no chroot necessary when using LiveCD environment>>
5. rsync --delete-after --force -aAHPWl
--exclude-from="/root/centos7-rsync-exclude.txt" / root@10.10.10.200:/
<<----the host address of the server to receive the sync/copy.
((that's a lowercase "L" after "-aAHPW"))
6. the "centos7-rsync-exclude.txt" file contains:
boot
dev
etc/fstab
etc/grub2.cfg
etc/mtab
etc/default/grub
etc/networks
etc/sysconfig/network*
etc/sysconfig/kernel
etc/udev
lib/modules
mnt
proc
sys
tmp
var/lock
