Thus once running (and I'm not suggesting that it is a simple task), migrating servers from CentOS 5.x to 6.x or perhaps to Debian or Ubuntu becomes a relatively simple task as the configuration details come from the puppet server.

If it is possible to abstract the differences, perhaps you aren't
using all the new features and didn't have to upgrade after all...
