User Profile Wizard (Corporate Edition) is profile migration software that allows you to move a local account to a domain account in under 30 seconds, regardless of profile size. This is useful when joining a machine to the WIN domain that already has users. It uses a mix of ACL editing, file ownership changes, and links on disk to leave files where they are but make them accessible to both users.
How to obtain
The User Profile Wizard (Corporate Edition) is licensed for use by current MIT Faculty and Staff on MIT-owned machines only.
