In this tutorial, we will show how to convert a Joomla 1.5 template to Joomla 2.5 template. We will take default Joomla 1.5 template "rhuk_milkyway" as an example and convert it to Joomla 2.5 native compatible template.
This tutorial covers only template conversion process, so it's assumed that you already have Joomla 2.5 website installed or converted from version 1.5.
There are 5 steps involved.

Joomla 2.5 introduces new file "template_preview.png" to present big preview image of the theme. You need to make a 640x480 screenshot of your theme and name it "template_preview.png".
Now, you need to edit file "templateDetails.xml" to make it compatible with version 2.5.
This is very cool feature of Joomla 2.5. Now you don't need to declare all files in some folder, you just need to declare that folder.
Add 2 following tags:
After editing file "templateDetails.xml", you need to continue to edit file "index.php".
Add code string "JHtml::_('behavior.framework', true);" to the location as seen on screenshot bellow.
Joomla 2.5 allows you to get theme name directly from file "templateDetails.xml" file, so there is no need to declare theme name as plain text.
Now, the converted Joomla 2.5 template is presented in templates folder, but you won't see new theme in Template Manager, because it's not installed yet. Make following steps:
