It really depends on the raid you have.
is it software or hardware raid?
if it's software raid it will be more then simple to do it while taking 
one drive out put a new one in and use let say FINNIX linux from 
cd\dvd\usb and manage the whole partitioning copying etc from another OS 
while not harming anything in the old HDDs.
you will might need to setup a new partitions manually on the new drive 
but just make a plan try it on some small VM to make sure the steps you 
are doing are fine for centos 5.5 and go for it.

rsync is your friend!! in this case.

someone mentioned here Gentoo which one installation of the system can 
give you very big backgorund on manual partitioning chrooting and other 
basic stuff that can help you in the process.
