Machine Cutover migration: There is a scenario where users have 2 profiles (old profile: user.lastname), and (working profile: user.lastname.domain).

There is a scenario where users have 2 profiles (old profile: user.lastname), and (working profile: user.lastname.domain).

The ReACL profiles and the machine cutover migration are done successfully, but, when the user logged on, the OS is using the old profile (user.lastname) instead of the working profile (user.lastname.domain).

Question: We do not want to touch the user data. Is there any way to instruct the OS to use the working profile (user.lastname.domain), or is there some way to do it through the Binary Tree tool?, or some suggestions from your expertise?
