PHP Server Upgrade from 4.4.8 to 5.2.17

My current webserver is running PHP Version 4.4.8 and we plan on upgrading to PHP Version 5.2.17.

As I have a lot of custom scripts, we're going to go through a proper test phase, but I just wondered if anyone knew of some good articles or had some experiences on what I need to watch-out for.

This page has an article about upgrading PHP.  I went from 4.4.9 to 5.2.5 then 5.2.17 on this computer without problems.  The MySQL connection can be a problem depending on the driver and database version that you are using.

Upgrading to PHP 5.3 is a much bigger step if you were wondering, especially if you are using Microsoft SQL Server.

Thanks Dave - I won't be doing the upgrade myself, my web-host will be.

I was more wondering about changes that might cause bugs within my php scripts.

Thanks Dave, much appreciated.

Yes we're going to do some full Regression testing before we move to the new server which will be running 5.2.17.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
