When a person or people move between sites, Identity Manager is not able to copy their profile to the new profile server because we use V2 profiles (available since Windows Vista i.e. 2007) and D1IM is not looking for \profile$\userid.v2
V2 profiles are not currently supported in 6.1.x
This feature is currently not supported out of the box, but it is possible to build customization to support this with the professional services team.
Enhancement Request ER13607 has been submitted to Development for consideration in a future release of Identity Manager
