Hi!

What is the best way to migrate from one active directory to another? I.E. from Contoso.com ---> Contoso.local?

Question,

contoso.com will still be running once contoso.local is created ? or you'll delete it ?
You have the option of renaming your domain !

Let's supose you want to have contoso.local just for your local users, and contoso.com for your internet front. You won't have many users defined in contoso.com, so...it would be better to rename actual contoso.com to contoso.local, and install a new DC for  server contoso.com

If it is not the case...try to explain it a little bit, so I can be more helpful ;-)

Saint...

contoso.com is active now, and on a separtate server i'm going to set up contoso.local -so both will be active during the migration - the idea is to slowly move from one to the other.

contoso.com was not set up properly, so once the migration is complete contoso.com will be deleted, and then rebuilt.

i need to make sure all user settings are migrated...documents, mapped drives, email (outlook settings for POP3 not exchange), printers, program settings, etc. Is there a script that will do this? A program?

Let me know what you think...

Well,

to move all the object from one domain to another, I'm sure you will find good stuff at microsoft's script center site (http://www.microsoft.com/technet/scriptcenter/scripts/default.mspx). You can create some script to download al the information you need regarding user account, and then import them using another script to the other domain.

Regarding to the information about POP3 account and user documents...once you join a computer to the new domain, and the user logs in for the first time, a new profile will be created. Let's say my account in AD was 'Saint' at the old domain...and I have a profile in my local computer in C:\documents & Settings\Saint . When I have my account created at the new Domain, and I loggin for the first time in my computer, a new local profile will be created...but since a profile with my username already exists (for the old domain), Windows will create a profile "contoso.saint" under Documents and Settings. All you have to do once the new profile is created is to logoff, login with a local admin account, and copy all the files and folders from the old documents and settings\Saint, to the new documents and settings\contoso.saint. Be sure you have the option "show hidden files and folders" enabled in your windows explorer.
Remember to delete all the stuff under Temporary Internet files...because it could take a looong time to copy from one profile to another if you don´t do that...
Once you have copied all the files and folders, logoff and login with 'Saint' from new domain account. I think that would be good enough.
Let me know how it goes...!
Thx,

saint.
