Update Red Hat Linux Enterprise install

I am very new to Linux.

I am trying to install an application (StrongMail MTA) on a Red Hat Linux Enterprise vmware image.
When I run the installer it tells me the following -

 OS Found: Red Hat Enterprise Linux ES release 4 (Nahant Update 4)
    Supported OS List:
       Red Hat Enterprise Linux ES release 4 (Nahant Update 7)


So my question is, what is the quickest easiest way to update from Nahant Update 4 to Nahant Update 7?

Can I use Up2Date or Yum ?

redhat 4 had up2date and you may need to have a valid contract to access rhn.redhat.com

RH 4 is more than 6 years old.

The current release is RH 6.1

Try CentOS, redhat enterprise Linux clone (pretty much build from the same source code).
http://www.centos.org/

Free updates and most of third party application work on RHEL can run on CentOS.

Based on some googling around, it sounds like I can upgrade my REHL 4.4 to CENTOS 4.7.

I am trying to download centos 4.7, but every download site I find has empty folders for 4.7.

Any suggestions?

Most of sites keep only 4.8 and 4.9.....

I was able to download the the CentOS 4.7 iso image and mount it as a cd on my vmware server.
But if I boot from the CentOS cd it doesn't want to upgrade.  It only wants to do a fresh install.

Also,  on a backup of the vm image I tried doing a yum update.  
This updated me to CentOS 4.9.
But the software I am trying to install doesn't seem to like 4.9 and says 4.7 is the highest 4.x version it supports.  Also, it says I can use 5.3 or 5.5, but now 5.6 is the latest.

So I am thinking that I will have to do a clean install?
you can install and try

Centos is based on RedHat, but there is no upgrade path from RH 4.4 to Centos 4.7.

I think you could/should upgrade to update 9.
Check the install script if it is a shell and it is likely looking for 4.7 or newer which 4.9 will be.

You download CentOS 4.7 which is the version you need. Why do you need to run yum upgrade for CentOS4.7?

By the way, you can download CentOS 5.5 here

centos 6 is also available. replace the 5.5 with 6 from the above link.
But presumably there is a reason why you are using RH 4.
replace 5.5 with 4.7 or 4.9 and you will get the respective centos version for the RH 4 you are looking for.

A lot of software check the OS release version during the installation due to compatibility issue with glibc or some other system libraries.

Try CentOS 4.7 or CentOS 5.5 without run "yum upgrade" and install StrongMail MTA to see if it works or not.

Thanks for all the advice.

I ended up doing a clean install of CentOS 5.5
