If it runs *cleanly* on PHP 5.3, then it will be fine with PHP 5.5. Enable all warnings with PHP 5.3 and see what it tells you. A number of things were removed between 5.3 and 5.5, but you will be warned about them in 5.3. * http://us1.php.net/manual/en/migration54.incompatible.php * http://us1.php.net/manual/en/migration55.incompatible.php
