While there is often times a way to do things if you really want, keep in
mind that this is not a RH supported method, which means they won't want to
support that system post install.  Which removes most of the reason to use
RHEL.

Upgrading from RHEL5 to RHEL6 is akin to going from Fedora 6 to Fedora 13.
Fedora supports OS upgrades using the 'preupgrade' utility which was
released at Fedora 9 (i believe), but I am pretty sure it only supports
direct incremental upgrades (9-> 10, 10->11, etc).

Its probably something someone can successfully accomplish, but the risk
factor (IMO) is very high.

Text install is performed the same way it always has, when using boot media
enter "linux text"
