There are many reasons why you should be upgrading your website from Joomla 1.5 and leaving the old Joomla behind. We're finding that more and more clients that we are working with need to now move away from the old legacy CMS and upgrade to the more current version.

This article goes through a few reasons why you should be upgrading to the latest version of Joomla with some pointers that you can tell you clients to help persuade them to upgrade their websites.

Here are my top 5 reasons to migrate and upgrade from Joomla 1.5.


Joomla 1.5 websites have the potential to invite hackers in, and maybe stay for a cup of tea while they’re at it.

From September of 2012, Joomla 1.5 no longer received support and updates. Migrating from Joomla 1.5 to 2.5 or 3.0 is vital to keep hackers out, minimise downtime and to keep your site secure. 

I've seen so many hosting providers that are running PHP version 5.2, which is a very old version of PHP on your server and opening up your Joomla site to potential hackers that are taking advantage of the old servers. Joomla 3 needs to run on a PHP 5.3 server ensuring that the server environment is more up to date for added security.

Consider asking yourself what would be better, suffering considerable downtime when your site gets hacked as your site is being migrated to the latest version of Joomla or spending the time now while your site is still up and running to safely migrate to the latest version without any downtime at all.


Extensions are no longer developed for Joomla 1.5, so you’re putting your website at a disadvantage over the competitors. Do you want a site that is boring and out of date? Consider the migration a time to refresh and revamp your site. Support for Joomla 1.5 extensions is no longer available, which can lead to vulnerable or unstable extensions on your site.

Of course there are a handful of extensions that are still being developed for Joomla 1.5 but in reality, all the good ones are no longer supported.

One-Click Updates

Once you have migrated from 1.5 to 2.5 or later, Joomla has incorporated a simple one click upgrade feature for future updates. Forget the hassle of the initial update/migration!

Once you've done the hard work now, the rest should be easy street and simple to do. 

Greater Search Engine Optimisation (SEO)

Do you want more traffic to your site? Get higher search results in Google, with Joomla’s improved SEO, which also helps when searching from within the site.

New search capabilities have been added to Joomla which make is so much better than Joomla 1.5. The internal search itself is very much improved making it possible to search for content within the site. 


Get up to date support from Joomla. With the guarantee of Joomla 2.5 as a long-term support release, you can be rest assured that you will have official Joomla support until 2014. Third party Joomla agencies will love you as well. There is nothing worse than picking up a Joomla 1.5 and needing to support it. More and more resources and support tools for Joomla 1.5 are becoming obsolete making supporting them even harder.

Key Thing to Keep In Mind

You may have noticed while reading this article that I didn't really mention upgrading your Joomla website but rather migrate your Joomla site. The move from Joomla 1.5 to 2.5 or later is a website migration and not a website upgrade.

The changes from Joomla 1.5 to Joomla 2.5 were so substantial that a simple upgrade which so many of us are use to isn't possible. So keep that in mind when making the change.
