A little about the Solution Accelerator (from TechNet page)
“With the release of Windows® SharePoint® Services (WSS) 3.0, users who have created sites based on any of the original WSS 2.0 application templates offered on Microsoft TechNet or on other customized sites or site templates will want to upgrade them to work in the WSS 3.0 environment.
The Solution Accelerator Team (SAT) has created a solution accelerator that provides guidance and tools to enable IT Professionals to successfully upgrade their Windows SharePoint Services 2.0 custom sites and templates. The result: a set of custom sites and templates that will operate in a Windows SharePoint Services 3.0 environment. This toolkit also includes a set of upgraded Windows SharePoint Services 3.0 application templates.”
I posted about this SA before; it has recently finished production and went up on TechNet. At this moment this is the only place on WWW linking to the SA TechNet page, a sneak preview if you will. The team, and me personally, are looking forward to your feedback.
