Switching AD domains in Windows 10 without losing data?

Question

I have a Windows 10 workstation joined to AD domain MyDomain.local . I log into the domain as MyDomain\UserMe.

I have created a new AD domain called MyDomain.com and my login will be MyDomain\UserMe (yes the pre-2000 domain name is the same in both domains)

I want to join my workstation to MyDomain.com and get rid of MyDomain.local at some point. I believe that when I do this and login to Windows 10, I will have lost all of my app settings and will have to reconfigure several installed apps. Is that correct ? is there any way to copy my app settings from my UserMe@MyDomain.local profile to my UserMe@MyDomain.com profile on the Windows 10 machine ?

Answer 1

Logon to the new domain once then logon to the pc with another account that has local administrative rights, navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

find the new profile, and point the Reg_Expand_Sz string named ProfileImagePath to the old domain profile.

The user may need to take ownership of the profile folder structure under C:\Users
