To run WordPress your host just needs a couple of things:
PHP version 5.2.4 or greater (recommended: PHP 5.4 or greater)
MySQL version 5.0 or greater (recommended: MySQL 5.5 or greater)
Source: https://wordpress.org/about/requirements/
I understand the requirements, but I’m talking about running a currently working site using PHP 5.2 that is to be upgraded beyond my control to 5.5
What do I need to do on my end to hopefully ensure zero downtime?
Hi,
WordPress is all good between PHP versions 5.2.4 and PHP 5.5 or greater. Hence, there are very little chances of a PHP update breaking your WordPress site. Although, your web host will take every precaution they can to make sure that everything goes smoothly and customers don’t feel any glitch in the service, you should take full backup of your WordPress website at your end. Additionally, make sure that you WordPress website and all plugins are up to date. In case if some plugins may stop working, you need to contact the plugin author for support.
Thanks,
What version of WordPress your currently using?
In general, its always recommended you keep your blog updated, specially plugins. The security risk of having outdated blog and plugins is high.
I’m currently using 4.2.2
The webhost FAQ about the upgrade says the following;
The following PHP settings are no longer supported in PHP 5.5 and therefore disabled:
register_globals
register_long_arrays
allow_call_time_pass_reference
y2k_compliance
magic_quotes_gpc
magic_quotes_runtime
magic_quotes_sybase
safe_mode (and all related settings)
Its down to waiting until they update to 5.5
The most important thing is to make sure you backup your website. Once the PHP update is done, fully check your website and come back here to post any errors/problems your having.
Once again, its always recommended you keep your blog and plugins updated.
