In this short tutorial, we will inform you how to migrate your previous Joomla 2.5 to newest Joomla 3.3. Are you planning to upgrade your Joomla version? Then, you have entered correct blog here. :)

Things You Need to Check

1. Please identify your Joomla extensions (3th-party components, plugins and modules) that may have compatibility issues with

the newer Joomla 3.3. You may need to check on project website or contact with developers to see if there are newer versions that you will need to reinstall. Remember that Joomla 3.3 also continues the move away from Mootools based javascript with the Joomla core, and towards the JQuery user interface. If current, used component don’t have new updated version you have two options: wait with migration/upgrade until it will be available (for example VM) or use alternative, replacement component which have similar features.

2. The second thing you need to check is please make sure your hosting allows you to install Joomla 3.3. The minimum required PHP version is now 5.3.10, but it is highly recommended that servers are update to the latest version of PHP 5.4 (or 5.5) for best performance, security and compatibility. If you doubt that your hosting provider offer the latest PHP 5.4 or not, then please kindly contact their support team.

3. This is very important for you. In order to avoid any problem, then you need to make sure that you have backup everything (files and database). Most of hosting provider will do daily backup, but we would recommend you to backup it on your end too. That way, if something goes wrong during the upgrade process, you can easily restore your site to the earlier version and wait for professional help.
