Joomla 2.5 will reach "End Of Life" at midnight on December 31st. That's coming up soon! At that time, Joomla will no longer provide bug fixes, features, or security updates for version 2.5. All focus on updates, fixes and security will be on Joomla version 3.
So, for security, compatibility and performance purposes, now is the perfect time to make sure you have the latest available update of Joomla (3.3 or higher). Whether you just need a simple update, or you're ready for a major overhaul, 'Universe Design' can handle your Joomla update for you, to help ensure you, your site visitors and customers have as smooth an experience as possible.
The great news is, the Joomla Programming Leadership Team has gone to great lengths to ensure the transition from 2.5 to 3.x will be less the tricky migration path of old (think of the horrors of upgrading from 1.5 to 2.5), and more of an update.
When updating your Joomla site from 2.5 to 3.x on your own, don't forget, it's important to make sure your templates, plus all of your extensions — components, plugins and modules — are ready for the update to the new responsive and mobile-ready version of Joomla too. At 'Universe Design', we always recommend backing up your entire site, and testing the site updates or upgrades on a development (separate, private) server first, to ensure all data and content is intact, and all functionality is properly operating, among other testing methods.
