PHP Upgrade

[chris1888]

Currently running PHP 5.2 with VB 3.7 Would like to upgrade to 3.8.9 so I can run PHP 5.5

My question is can I wait with the PHP upgrade until AFTER I upgrade vBulletin from 3.7 to 3.8.9? Will 3.8.9 work with PHP 5.2 until I upgrade it to PHP5.5?

This is the first time I will be upgrading, any issues I should pay attention to? Only installed addon I can think of is vbseo.

Thank you

vBulletin 3.8.9 requires PHP 5.3.0 or greater, and MySQL 4.1.0 or greater, and cURL to be installed.

So you need to upgrade before you install/upgrade vBulletin. :) Be sure to get a complete backup of your site BEFORE you upgrade PHP, MySQL etc.
