When we need to tranfer multiple PC’s from one Child Domain say A to another child domain say B in same forest. Instead of creating teh User account and computer account again we can use ADMT tool to migrate user acount and computer account from A to B.
Benefit of using ADMT tool is all users settings will also get migrated so when user will log into new Child domain he will not face any issue only he will be sitting in new place but working with old settings.
Even when we use ADMT tool exchange server mailboxes also get transfered. which is also a good feature.
Downlaod ADMT tool from Microsoft site and install it on Source or target Domian controller and foillow the next steps
Here it will show us the no of user / computer accounts migrated.
