I am using TFS 2010 Team Project Collection and I migrate branches of collection into the same collection. The solution source control is included in the branch folder.
When I migrate I got the error,
"The following path is not mapped in the target system: $/Project/Dlls"
and same error that the same number of my branch folders.
Microsoft.TeamFoundation.Migration.Toolkit.MigrationException: Checkin failed for unknown reason at Microsoft.TeamFoundation.Migration.Tfs2010VCAdapter.TfsVCMigrationProvider.ProcessChangeGroup(ChangeGroup group)
