I like to keep reasonably up-to-date with distributions I am running, so would like to update to Centos-5.2 as and when it is released.
you will be up to date simply by running 'yum update'
When 5.2 is released, those updates will be installed
For the record, I upgraded my server to Centos-5.2 without any problems. It was in fact the easiest system upgrade (if you can call it that) that I recall, in many years of system upgrading.
