We've got about 200 existing servers running CentOS/RHEL 5.6 and all new servers are being provisioned using CentOS/RHEL 6.1. So that everything is consistent we need to upgrade the servers running CentOS/RHEL 5.6. I've searched the CentOS wiki, the Red Hat site, and the internet looking for something official on upgrading/migrating from CentOS/RHEL 5.x to CentOS/RHEL 6.x. There's got to be a way other than having 2 times hardware.

Backup your data/configurations, reformat, re-install your data/configurations.

There is no other "official way" to change from v5 to v6.
