How to upgrade Joomla 2.5 to Joomla 3.x

* Updated in December 2015

Joomla! 3.0 was released a long time ago (and now the latest version is Joomla 3.4), so if you want to upgrade your website from Joomla 2.5 to Joomla 3.x, you can follow the steps below. Let's take a look!

Before you decide to upgrade your Joomla website:

  • Joomla 3.4 is the newest version, recommended for most new installs.
  • Not all of third-party extensions are a one-click upgrade.
  • Upgrade Joomla! from 2.5 to 3.x

    1. Back-up your website

    To back-up your website, you should use Akeeba back-up. If you do not know how to back-up your website, you can read instructions here: How to use Akeeba to backup your site..

    2. Check to make sure all your running extensions are the latest version

    In your Joomla back-end, check the "Extension Manager" to make sure that you are running the latest version of each extension.

    5. Check all extensions / templates for Joomla 3.x compatibility

    You need to check all the templates and extensions that you want to use on your website to make sure that they are now compatible with Joomla 3.x. Some Joomla extensions do not support Joomla 3.x

    6. Create a test site

    If your website meets all the requirements above, you should create another back-up site and a test site on your server in a sub-folder. If you don't know how to create a test site, you can read a tutorial from Ostraining here.

    7. Try upgrading in the test site first

    • In Joomla test site back-end, go to Components -> Joomla! Update
