I couldn't find specific reference to installing the Scrum template onto SharePoint 2010 so I thought I would confirm that it does indeed work. A few tips:
- The MSI installer does not apply the process template nor install the SharePoint feature. You need to upload the template manually and run STSADM.exe commands to deploy the TFS WSP. Follow the ReadMe.txt files in the installation directories for the template and the feature, respectively.
- The path in the SharePoint installation ReadMe.txt file refers to the STSADM.exe path in the "12 hive" but this switches to the "14 hive" for SharePoint 2010. Just replace the paths to ../12/.. with ../14/..
