When using a "Import Mapping" file to rename logon names (samaccountname) to the target environment with Migration Manager for AD, the new logon name may not be displayed after processing a machine when the machine reboots. It will show the old source username.
For example, after migrating the desktop of a user the workstation is rebooted. The logon screen displayed shows "target-domain\source-username" instead of "target-domain\new-target-username."
The "Move" log reflects it did not find the "new-target-username" and thus defaults to the "source-username."
How do you ensure, after desktop migration, the new user logon screen will be displayed at the logon prompt with the proper account?
