I contacted them myself when the DVD kept refusing to find the
installed OS. Here is the response:

"An upgrade from RHEL 4.9 to RHEL 5.6 is not happening due to the fact
that there is a change in Major number between the 2 releases.

Inserting a DVD of RHEL 5.6 would provide you an option to Upgrade if
your Operating system were to be : RHEL 5.5.
This is possible because there is just a minor change in these versions.

RHEL 5.5 ==> RHEL 5.6 : Using RHEL 5.6 DVD : Up-gradable
RHEL 4.9 ==> RHEL 5.6 : Using RHEL 5.6 DVD : Not Up-gradable

Also,

RHEL 4.9 ==> RHEL 5.0 : Using RHEL 5.0 DVD : Not Up-gradable.

Every Major Release for example 4.x, 5.x, 6.x can be upgraded within
its range of minor releases i.e: 0-9.
However, to upgrade from a 4.x ==> 5.x, a fresh installation is needed
due to a platform change."
