Data loss due to folder move from source folder not under migration to destination folder under migration
This kind of data loss occurs when there is a folder move event between a folder (Source) not under migration to another folder (destination) under migration in Visual SourceSafe. After migration, the moved folder appears in the destination folder as if it was added when the folder was actually moved. The history of the moved folder and the items inside it before the move event is not migrated into the Team Foundation source control. In order to prevent such a loss of history, migrate source and destination folders of the moved Visual SourceSafe folder together.
