I have a Joomla 2.5 template and I want to make it compatible with Joomla 3.x?

Are there any resources out there that I can use? I basically need to know what has changed, deprecated methods, common problems?

I am not looking for detailed descriptions, just some starting points (links).

  • Hello Amirali, actually, I am not that sure if this question is on topic or too broad... So other JSE members may decide. Truth is there are some special notes regarding making a Joomla 3 template or upgrading an older one... but yet the whole process can be long enough, constituting a tutorial like answer... Below I posted some links to resources for helping you with your research.

Some links that might be of help:


The process of converting a Joomla 2.5 template into 3.4 is removing deprecated and removed functions.

It's more difficult if the template has older legacy functions from Joomla 1.6, and 1.7.

Here is a reference that could help https://techjoomla.com/developers-blogs/joomla-development/joomla-30-conversion-changes-needed-when-converting-a-common-installable-package-for-joomla-15x-a-25x-to-joomla-30.html

Note: A template is just a specialized type of extension which is why I'm sharing an extension upgrade reference.


Simple answer. Don't bother.

You'll spend a lot more time attempting that than either finding a similar looking Joomla 3 template and customising it or just creating a new one yourself. Joomla 3 templates are now designed as responsive and have left behind many deprecated functions from 2.5.

    Actually that is not always true. I have done a lot of Joomla 2.5.28 to Joomla 3.4.5 migrations in less than 30 mins. It all depends on the complexity of the template and any underlying PHP Framework it does or doesnt use.
