Update from RHEL AS 3.0 update3 to update4.

[Anant S Athavale <asa isac ernet in>]

Dear Members,

I have a system installed with RHEL AS 3.0 update 3.  I find on the net that,
Update 4 CD's are available.

The system which is installed with update3 is not connected to internet and will
not be connected to internet for security reasons.

Now, please suggest me, how can I update the system from update3 to update4
using the downloaded CD's from internet.

Thanks in advance.

Regards,
Anant.
