Advise applications under CentOS to clone the entire system.
You need to create an ISO image on one server and via IPMI to connect to boot and restore it on another server.
Tried clonesys — his outdated USB drivers, so at boot time it is impossible to answer the questions of the loader via KVM.
Acronis — expensive license.

thanks in advance.

. well, if perverted, then you can dd to write to stdout, and on the other side via nc or ssh to catch up on loaded the PXE server :)

I think the option of installing and rsync -az -e ssh / new@server:/ would be much easier.
