How can existing CMS 2002 customers migrate to Office SharePoint Server 2007?

Microsoft supports automatic data migration from CMS 2002 to Office SharePoint Server 2007. You can use Office SharePoint Server 2007 features such as search, master pages, and authentication UI to retire custom code that was created to implement these features. The remaining custom code must be migrated manually.
