Backup works. Or, create an image of your server on a spare drive
before upgrading and test the upgrade on that secondary/image OS
before trying it on your live system disk. You could also use
Radmind for package removal, if you already had it deployed.
No matter what, testing should be done before taking anything live,
no matter how tempting that glowing Install button is, especially
when considering applications that have been created in house, as
Apple and the developer community probably didn't test against them
beforehand. :)

It's the correct answer.
So, that's one of the things that bugs me about OS X. There is no way
for managing packages. If I'm running Debian or FreeBSD, I can handle
this situation _without_ restoring from a previous backup. Hell,
even MS
Windows supports this sort of thing.
There are numerous reasons why restoring from a backup may not
practical. Those aside, yes, in ideal world, it would be nice to
have a
system snapshot before you make any serious system change. But,
how do
you quantify "serious"? So, lets move from an ideal world to a
practical
one. The basic facts are, administrators sometimes forget things
or make
poor decisions. There is a level of fault tolerance that makes a
system
"usable".

This is the reason you never touch a production server (serious
change or not) until you have verified a change works as expected
on a development server.
I experienced this with a web application having awful performance
on Tiger, while with the exact same config worked perfectly on
Panther. My situation would have been avoided had I tested the app
on Tiger before doing an upgrade.
Also FWIW, I do not upgrade anything unless it has an impact on
things the server runs. I have not upgraded any of my servers to
10.4.4 because I have not needed to. Upgrading "just because" will
lead to trouble eventually.
