leaving a domain - data migration to local user


  • Hi,

    Is my user's data going to be safe if I leave a domain? Under what circumstances do I risk losing the data I have on my computer? I'm trying to get some computers out of a domain that belongs to a DC which they no longer have anything to do with. So I'm a little bit worried about data loss and stuff like that. What should I be concerned about exactly and is copying the user's profile to the new local user be enough to migrate all the data smoothly? I have several e-mail accounts configured, very particular programs and so on and so forth.

  • Hi,

    you are not going to lose any data (as long as the profile is indeed 100% local and is not using Folder Redirection) but you will be logging on as a different (local) user so will not retain the same user profile. Backup the profile by USMT prior to taking the computer out of the domain, then restore it back to the new (local) user.

    You might need to adjust permissions on those folders that are outside of the user profile.

    Do verify you have a valid local Administrator account with a known working password before you remove the computer from domain.

  • Hi,

    If you leave the domain, the user profile will still exist, but you won't be able to log into it because the computer will no longer trust domain accounts for any purpose.

    You won't be able to access your domain account unless you take steps to convert your domain account to a local account. There are several guides detailing how to do this, but basically it boils down to creating a new account and copying over all files from old domain account to that newly created local account:

    Please refer to the following article to get more detailed information:
    How to convert your Domain Profile to a Local Profile.
