Support » Fixing WordPress » Updating site from very old version

  • Hello,

    I am using a very old version of WordPress – v.2.3.1 which has been performing with no major issues for the past several years.

    Can I update to the latest version of WordPress? And if I do, will it affect any of the formatting, text, videos, layout on my website? Are there new security features with the new updates?

    Thanks.

    Yes, yes and yes.

    There have been multiple overhauls since 2.3.1 and you may find it a bit of a shock. Your plugins may break, your theme should still work (though not optimally) and there are a LOT of secure fixes.

    Good place to start reading about the upgrade process itself:
    http://codex.wordpress.org/Upgrading_WordPress_Extended#Detailed_Upgrade_Instructions_for_1.5.x.2C_and_versions_2.0_-_2.6.5.2C_to_3.1

    In general, running a version that old is just an open invitation to hackers. As each new release came out, security flaws in the previous release were documented for all the world, including hackers, to see and, in the case of hackers, to exploit.

    Make sure your PHP version is current before upgrading.

    from http://wordpress.org/news/2010/07/eol-for-php4-and-mysql4/

    For WordPress 3.2, due in the first half of 2011, we will be raising the minimum required PHP version to 5.2. Why 5.2? Because that’s what the vast majority of WordPress users are using, and it offers substantial improvements over earlier PHP 5 releases. It is also the minimum PHP version that the Drupal and Joomla projects will be supporting in their next versions, both due out this year.

    In less exciting news, we are also going to be dropping support for MySQL 4 after WordPress 3.1. Fewer than 6 percent of WordPress users are running MySQL 4. The new required MySQL version for WordPress 3.2 will be 5.0.15.

    Thank you for all your feedback. I have updated to PHP version 5.2.5 and am working on updating MySQL to version 5.0.15. Is there anything else I should do before hitting the update button? I am quite nervous about losing the plugins (although I should be able to reconnect them, right?) and not having the theme run optimally (does this mean more slowly, or will it affect the layout?) My theme is Blueflower 0.5

    Thanks again.

    Most important I can think of http://codex.wordpress.org/WordPress_Backups

    thesse upgrade will not affect theme layout; newer PHP and SQL might mean a few milliseconds faster server

    I’d also recommend that you carry out a series of smaller upgrade steps rather than 1 single massive upgrade – eg: 2.3.1 -> 2.5 -> 2.7 -> 2.9 -> 3.0.4 -> 3.1
