stsadm.exe -o migrateuser
-oldlogin
-newlogin
[-ignoresidhistory]

Stsadm.exe –o migrateuser –oldlogin xyz\Ramesh –newlogin abc\Ramesh -ignoresidhistory

By using this we can maintain the old login permissions with the new login in the migrated domain.

Stsadm.exe –o migrateuser –oldlogin xyz\Ramesh –newlogin xyz\RameshBabu –ignoresidhistory

We need to add the – ignoresidhistory must to run this command as it will ignore the previous SID history.
