SharePoint 2007 – SharePoint 2010 Upgrade Definition File (UDF)
As part of the upgrade planning using DB attach method, we can define Upgrade Definition File (UDF) which will transform the file definition or features to be activated/depreciated upon upgrading SharePoint 2007 database to SharePoint 2010 web application.
You might have custom site definition in sharepoint 2007, and you’d like to do some actions/transformation upon upgrading sharepoint 2007 to sharepoint 2010 such as changing file mapping, activating new site/web features, etc. this is where UDF file comes in handy to help us how we’d like to upgrade sharepoint 2007 site.
You can get more reference on UDF based on the following article:
What’s a good sample UDF? You can find from the existing SharePoint 2010 UDF file in C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\CONFIG\UPGRADE\ folder. You’ll be able to see a lot UDF file samples.
Some of the explanation on the above definition
File : Describes the relationship between an existing provisioned file to its equivalent file for upgrading to Microsoft SharePoint Foundation 2010, specifying how setup paths of files in the previous version map (relate) to setup paths in the new version relative to their %ProgramFiles%\Common Files\Microsoft Shared\web server extensions\14\TEMPLATE directories.
AppliedWebFeatures Element: Supplies a list of Web site Features to be marked as "provisioned" for Web sites created in Microsoft SharePoint Foundation 2010. For example, an announcements list template of the previous version must be mapped (related) to its equivalent announcements Feature in the new version.

That’s a log from sample UDF file that I made for my custom site definition. In this sample, I’d like to activate some new features when I upgrade my sharepoint 2007 site which is based on my custom site definition. Some of the new features that I’d like to activate when I upgrade to sharepoint 2010 will be like preparing new master page so that it’s ready when I’m planning to switch to V4 UI version, etc.
This UDF file can be made to match our new site definition in SharePoint 2010.
