This tutorial provides instructions for converting a Joomla! 1.0.x template to run in Joomla! 1.5 native mode. The classic rhuk Solarflare II template is used to illustrate the steps one must take to accomplish this task. Rhuk's Solarflare II is one of the most popular templates ever for Joomla! and before that for Mambo. It was included in the initial Joomla! 1.0.0 release and before that with various releases of Mambo. I do not recall exactly when the initial version of Solarflare II first appeared. The version I used as baseline for conversion to Joomla 1.5 is dated November 2, 2004. A very telling tribute to its success is the many sites that still use it to this day and the number of "forks," or variations that one sees powering a ubiquitous and diverse set of sites. The last time I did a Google search on "rhuk Solarflare," I got about 78.5K hits. Pretty impressive!
