[CentOS] Upgrading my local repo to 5.2

This will be the first version change with my local repo so I want to 
check the steps out.

I have a /Centos/5.1 directory with all the contents of the ISO CDs.
I have a /Centos/5 directory with a symbolic link to the 5.1 directory.

I ASSUME that I will create a /Centos/5.2 directory and drop the 
contents of the ISO images there.
Then change the symbolic link to the 5.2 directory.
After I test out both installs and upgrades from this new directory I 
can trash the old 5.1 directory.


Do I have it right?
