We plan to provide migration tools for users switching to TFS. A VSS user asked in the newsgroup about migrating VSS labels, revision history, sharing, and pinning.
The goal is migration of all data, consisting of projects, files, and folders, with associated metadata reliably with minimal information loss while preserving user information and appropriate permissions. There are some features in VSS that do not translate to TFS. The following is quick overview of the preliminary plan.
That is a very quick summary of the plan, which may change. We welcome your feedback.
