You would need to lookup the changelogs on the redhat site for all inbetween versions and judge, if the issues apply to your setup.
A test update on a redundant machine is also adviseable.
I intentionally do not write the update command here.


Other than that: rhel 4 is ancient.
It is a better approach to backup data, configs, logs
and install a new rhel 6.2 (or a rhel clone)

I am doing on the test machine, to have practice of upgrade i am asking

then have a look here:

man up2date

Not sure if the repos are still reachable though.
As I said, rhel4 is very, very old

Yes, it is right better to update the redhat to higher version.
This link might be helpful to upgrade the redhat 4.x to 5.x

RHEL4 has not yet entered extended lifecycle, IIRC, when only critical security patches will be available, but will as of Feb. 29, 2012. Currently full update packages are still in the repos (I have currently entitled systems). You do, as always, need a current entitlement/subscription.

OP, you're wasting your time practicing on this. The standard update mechanism in current RHEL releases is yum, not up2date. Since this is test, I'd suggest installing Centos 5.x and updating that. I think you can still find 5.2.

As Mudgen said, RHEL 4 support will end in February 2012. You really should look into upgrading to RHEL 5 or 6. The latest stable release, 6.1, is very good. I am running that on my laptop now (Scientific Linux 6.1 clone of RHEL 6.1) and plan on upgrading my 6.0 workstation to 6.1 this weekend.
