You'll want to run, and resolve" yum list extras" when you're done.
Some components, such as gcc4x, and major version changes between
releases. Others were discarded. I'd start with the "*-release*
components and work my way, manually, up the chain, or pop in the
latest 5.6 media and use those for an upgrade procedure to resolve the
major component version update issues sucha as gcc4x.
