Today we have released an upgrade tool for users of VSS to upgrade to either on-premises TFS or the Team Foundation Service in the cloud! It provides a wizard-based UI for upgrading a VSS repository to TFS 2010, 2012, or the service.
Compared to the old VSS conversion experience, there are quite a few improvements.
With mainstream support having ended back in July for VSS 2005, now is a great time to move.
You can download it now and find the documentation here.
[UPDATE 11/14/12] We will be changing the docs to indicate that you are not required to have an empty team project collection or team project for this tool to work. However, we do not validate that there will not be a collision before the migration starts, so you will need to make sure that there is no path in the destination in TFS that will be the same as what you are migrating from VSS.
