Is there are a reason you are limiting your update to Red Hat Enterprise Linux
Release 5 Update 2 (5.2)?

Just keep several things in mind ...

1)  The DVD will only have the bugfix and security errata applied through that 
update

Red Hat Enterprise Linux Release 5 Update 2 (5.2) is over two (2) full years 
old 
(2008 May)

2)  Running an older update is no longer current with engineering and new errata

Red Hat Enterprise Linux Release 5 Update 5 (5.5) is current release update 
(2010 March),
and errata, support and other services will be focused on this release.  Unless 
your organization
has a known certification and support issue with 3rd party solutions, this 
should be the release
update your organization should be running.

3)  Red Hat offers Extended Update Support (EUS) for older release update 
support

#3 allows customers with independent software vendor (ISV) or other 
certification
lifecycle issues to remain several releases updates back.  Only limited 
security 
updates are
built for these older updates, and only for several updates back.

The current EUS offerings for Red Hat Enterprsie Linux Release 5 include ...
- Red Hat Enterprise Linux Release 5 Update 3 (EUS 5.3.z)
  http://rhn.redhat.com/errata/rhel-server-5.3-errata.html  
- Red Hat Enterprise Linux Release 5 Update 4 (EUS 5.4.z)
  http://rhn.redhat.com/errata/rhel-server-5.4-errata.html
In addition to the current 5.5 (and EUS 5.5.z)
  http://rhn.redhat.com/errata/rhel-server-errata.html  

The EUS support for Red Hat Enterprise Linux 5 Update 2 (EUS 5.2.z) ended in 
March:  

  http://rhn.redhat.com/errata/rhel-server-5.2-errata.html  

As you'll note, there have been several security errata issue since that time.

Red Hat Enterprise Linux releases are designed to maintain ABI/API 
compatibility,
ISV software compatibility and eliminate (or at least mitigate) regressions in 
upstream
software by backporting security and bugfixes, instead of rebasing to new 
versions.
  http://www.redhat.com/security/updates/backporting/  

This is one of the major values of the Red Hat Enterprise Linux subscription.
As such, updating to the latest Update is typically not an issue, unlike other, 
popular OSes.

Sustaining engineering is a primary focus of Red Hat Enterprise Linux, not 
pushing consumers
to always upgrade for features and, correspondingly, more sales.  Likewise, any 
subscription
entitles the customer to any release, including newer versions that were not 
released at the
time of the original purchase of the subscription, removing the feature v. 
compatibility delima
(let alone added costs) for the customer.

Sounds like a good plan, thanks Greg.
