I am running into some issues with a script not working properly on my production server,PHP 4.3.2, but works fine on my development machine, PHP 5. I am thinking of upgrading the production box to 4.3.11 or 4.4, scared to go straight to 5. My question is will there be any issues with upgrading or will it be a seamless transition.
Thanks in advance.
Pretty straightforward; there's a section in the manual on what needs to be looked at when migrating from PHP 4 to PHP 5. Don't forget to make a note of your configuration details (phpinfo(), php.ini) so that you can make sure the new install is configured the same as the old install. It would probably be simpler to go from 4.3.2 to 4.4, but if you're already using PHP5 then what would be the point? You'd just be putting off the inevitable.
