AD does not care about "humans". Different accounts are different
accounts,...whether the same human uses them or not is irrelevant.

This is a HUGE thing. You have to read the Docs for ADMT,....over and over
and over,...if you have to. This is not something that we can teach you in
a simple email message.

You don't "map" anything to anything. The New Domain Starts out EMPTY. The
ADMT tool "copies" the User accounts from the Old Domain into the New Domain
and optionaly Disables the old account in the Old Domain as it does it. It
can keep the SID History to the account so the Account keep the old SID
along with the new SID to smooth out the premissions during hte migration.
But after the migration is finished the SID History can be removed.

You don't map anything. The accounts in the New Domain are not supposed to
exist.
