I am in the process of planning the uprade of sportrline from 1.5 to 2.5-3.0
I found this handy guide from joomla org:
Alternate Method Using a Version 2.5 Template
Start with a basic template that works with a current version of Joomla. For this example, use the Atomic template that is supplied with Joomla 2.5.
Copy the entire /templates/atomic folder to a new folder in the /templates directory.
Rename this new folder. For instance, you might call it mysitename-atomic to designate it as the custom template for this site and adding the reminder that it was derived from the atomic template.
In the new template's index.php file, delete everything between the <body> </body> tags.
Copy and paste everything within the <body> </body> tags from your version 1.5 template to the body of the new template's index.php file.
Delete or rename the template.css file copied from the Atomic template.
Copy the template.css file from the old version 1.5 template.
Update the templateDetails.xml file in the revised template.
Change the <name> entry to match the name of the template folder. It is case-sensitive. If the folder is /templates/mysitename-atomic, the entry in the templateDetails.xml file will be <name>mysitename-atomic</name>.
Replace the <positions> section of the file so that they match the positions used in the index.php file.
Change the other elements as necessary. For instance, you might want to modify the creation date and version number.
Delete images in the /template/image file and add your images.
My concern is would i be better off using a generic template like yougrids to test this procedure in order to include YJSG in the finished product. I realize i will have to find alternatives to many of the modules sportline uses but i should be able to come close.
