There are compatibility problems between PHP 5.2 and 5.3. Some of your
code may require updating. Generally for that sort of thing I'd take an
image of the server in question and do the update on the image, qa the heck
out of it, have the fixes done as needed, and when I was confident, go
forward. Or, I would build a new system with the desired versions, and do
the same with the code.
This kind of legacy maintenance is the nightmare that sysadmins have to
deal with regularly.
