I'm using WordPress version 2.0.5. My hosting provider advise me to upgrade my WordPress software so that my website will work with latest PHP 5.2.1 and Zend Optimizer 3.2.2 when they adopt them later.
I have re-coded some php files for customizing my website. I do not want to replaces all files with the latest version in order to avoid re-code all the files I have recoded before.
My question is actually simple-- will WordPress 2.0.7 works fine with PHP 5.2.1 and Zend Optimizer 3.2.2? If so, I will only need to update a few files.
Thanks in advanced
