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.
The solution accelerator is comprised of three components:
- Upgrade Toolkit for Windows SharePoint Sites and Templates Guide
End-to-end guidance to plan and implement custom site and template upgrades.
- Solution scripts
Nine command line scripts to facilitate the upgrade process.
- Upgraded application templates
33 application templates that have been upgraded from WSS 2.0 to WSS 3.0.
