How to migrate from PHP 5.2 to PHP 5.3
Posted by Vincentas G on 04 February 2012 03:08 PM
We are glad to announce that Host1Plus fully supports PHP 5.3 and this guide will show how to migrate from PHP version 5.2 to PHP version 5.3. The new release of PHP 5.3 brought many important additions and changes to PHP. Although longly awaited, some of the changes are not backwards compatible. Thus, code that worked fine with 5.2 may produce warnings or fail in 5.3.

Quick research shows that most prominent applications had to be patched or changed, even though minimally, to work cleanly with 5.3. To help people to convert their web applications to 5.3, I present here a migration script that would allow you to inspect your applications for potential migration problems.

Most improvements in PHP 5.3.x have no impact on existing code. There are a few incompatibilities and new features that should be considered, and code should be tested before switching PHP versions in production environments.

More information you can find in php.net webiste under this link: http://us2.php.net/manual/en/migration53.php
There is also migration script available for migration to PHP verion 5.3: https://github.com/smalyshev/migrate
