Now that CentOS 6.0 is making its way to the various mirror sites, I wanted to solicit opinions on the upgrade process. In working with the commercial RedHat 5.6 and 6.x distributions for the past few months, I've been relying on a fresh install instead of an in-place upgrade for my test systems.
Since the real CentOS 6 release is here, is anyone planning on performing the migration in-place? Are there any situations where it makes sense? If so, what are the pitfalls of an in-place update?
