[CentOS] local centos repository upgrade from 5.3 to 5.4

Hi list,

I run quite a few centos 5.3 servers and have a local yum repository  
which is working fine.
Below a list of what I'm rsyncing at the moment + an extract from my / 
etc/yum.repos.d/CentOS-Base.repo file
I copied the OS directory from the install media and ran createrepo on  
that dir.

I would like to upgrade my servers to 5.4.
I was wondering if I could simply replace the '5.3' part in the rsync  
source to '5.4' ?
Or is there more to it?

Thank you in advance,
Kind regards,

Paul Herbosch
