There is a tool in the works, but last I heard it needs testing.

(But I'm a member of the fresh install camp!)

I need to upgrade a bunch of centos 5 servers to 6.x in the near future, mostly keeping the same connectivity and functionality. Are there any tools that will examine a running 5.x box and produce the appropriate /etc/udev/rules.d/70-persistent-net.rules (etc). to make the same box come up with the same interface names with the same IPs it had before?

I tried to install CentOS 7 on a new system. It works.

However, I'm noticing small things:
1. system-config-network-tui is not installed and yum cannot find it. I realized for this -- nmtui
2. What about firewall? I can't seem to understand the replacement from system-config-firewall-tui

Google gives many links to such a thing, but when I pursue them I do not get to an URL.
Where I can actually download one.
