It is not really a recommended approach upgrading from one major release to another (4->5, 5->6). You might want to consider doing a full install.

As far as I know there are no official RedHat documents available that describes an upgrade from one major version to another major version.

PS: If there isn't a good reason not to, why not update to RH 6.X, which is the latest stable RH version.

To add to the good advice that druuna gave, if you need to perform such tasks, the first people I'd ask would be Red Hat support...since you're paying for it with your RHEL subscription, right?? If you're not paying, then you should NOT use it, since all you're doing is running an unsupported/unpatched system, which will NOT receive bugfixes/security fixes/udates since it's not registered with the Red Hat network. Load the latest version of CentOS instead, which is 99.x% identical to RHEL, but FREE.

In-place upgrades (across major versions) are definitely not supported by RH https://access.redhat.com/knowledge/solutions/21964

Red Hat does not support in-place upgrades between any major versions of Red Hat Enterprise Linux. (A major version is denoted by a whole number version change. For example, Red Hat Enterprise Linux 5 and Red Hat Enterprise Linux 6 are both major versions of Red Hat Enterprise Linux).

They were not 'suggestions'...you CANNOT upgrade between major versions, period. Your application team may 'demand' whatever they want, but if YOU are the admin, then YOU provide the system. You don't 'demand' their application does something in particular, to have it suit you.

If you want more advice, contact Red Hat support, as has been suggested to you in the past.
