I'm migrating around 500 users from a windows NT4 PDC to a windows 2008 R2 AD. I have all the user information on an external database, so my idea is to recreate the users on the 2008 domain, instead of using ADMT.
What I'm not sure of, is if I have to give to the new domain, the same name used for the NT4, or if I can use a new one. Do you know what's going to happen to users local settings? I guess that if I use a different domain name, once the user logs into the local machine, a DOMAINNAME.username folder is going to be create. Is there any way to move the settings from the old folder?
Also we relay on groups to manage the way users access to file share. If I don't change the domain name, is this mechanism going to work? If I change the domain name, do you know if there is an automated way to map the permission so that:
OLDDOMAIN\group -> NEWDOMAIN\group
Thanks in advance
