Thank you all for the helpful and informative replies.  However, I have
some additional questions (interspersed below).

For some background, the organization I'm doing this for is a
significantly resource constrained, very small company, so I have been
having to take carefully measured steps in upgrading their systems and
bringing them into conformance.  In all cases, the systems were set up
by others prior to my time with them.

In particular, it would better, given their constraints, if I could get
their CentOS 4 system up to standards prior to migrating to a CentOS 5
system (which I'd already proposed to them).  Even migrating to CentOS 5
doesn't, by itself, solve my problem (see comments below).

How does one set up a test [web] server which has a number of sites, all
secured via SSL certs which are bound to the domain, and hence the IP
address, of the sites on the server?  They do have a developmental
server which uses one, company-issued SSL cert to secure all of the test
sites.  However, the Apache config for this is substantially different
than that for the production server.

It appears that I'd have to set up an additional, special testing DNS
space with new IP addressess, or to enter them into the hosts file(s) of
the web client test systems.  Also, I would not be able to simply copy
the httpd config file(s) from the production system to the test system
due to having to have different IP addresses for each site.  Or is there
some other way to do this?  I'm really stumped over this one.

Bob, your thoughtful, insightful, informative, and detailed reply is
very helpful.  Thanks!  My biggest hangup WRT the above is exactly how
to set up a test server that very closely mirrors the production server
without needing to have to maintain significant configuration changes,
esp WRT an SSL-secured web server.


On a related tack:

Even with CentOS 5, the available versions of, especially PHP and MySQL,
are not up-to-date enough feature-wise for the web site code on the
system, so later versions have to be used.  The httpd version is not so
critical in this case.  How can one cope with this situation, i.e., the
general situation of needing features not supported under a current
version of an OS so the vendor supplied updates are no longer
applicable.

In some cases I've been able to find 3rd party repos which have had the
RPMs I've needed (e.g., rpmforge, dag, epel, remi) but the ones needed
are not always available (as is the case now).  I have set up repos and
built my own RPMs in the past, but there is no budget for that in this
case.  Also, it is a lot of work, especially for a very few systems.
