Slightly longer: glibc is the building blocks that 1202 packages on my 
Fedora 7 installation rely upon. You would end up upgrading everything 
anyway, so you might as well install the current release if your 
hardware can support it.

on the existing system:
rpm -qa --queryformat="%{name} " > packagelistold.txt
backup the /etc /home /var {dbs etc}

on the new install:
do a minimal install {uncheck all packages and groups except yum - this 
leaves a bootable os}.
yum install `cat packagelistold.txt`

I have found in the past that:
- the packages line generated might be too long and needs to be split 
into shorter paths.
- some packages change names, and would have to be removed from the 
packagelistold.txt file.
