That can work with a certain amount of downtime while you install and 
juggle things although it's a lot easier if you can build the 
replacement on a different machine and swap it (or the drives) into 
place when everything works with a final rsync of data at the last 
minute.  If you plan to keep this running for years without 
reinstalling, Centos would be a better choice, since you can expect 'yum 
update' to supply security fixes for 7 years.

Centos5 would supply 2.1.9, so probably not a big difference.
