I've done this before, but in a slightly interesting way. Unfortunately, I did not make detailed notes so I can't tell you the exact commands I used.

Approximate sequence:

0) Back up everything you value, and make an install DVD with a kickstart file that enables installation over SSH or VNC

1) Disable the old OS's swap partition
2) DD the install DVD to the former swap partition
3) Configure grub to chainload the installation image
4) Reboot the server, and cross your fingers
5) Connect via SSH, complete installation via SSH or VNC
6) Once the OS is installed, change the former swap partition to be swap again and add it to /etc/fstab

Hope this helps!
