Hi kneureuter

Unfortunately, SMS cutover is unsupported on domain controllers. This has a workaround which may or may not be viable - demote the source, then promote after cutover. Of course can only be done if you have more than one domain controller.

The doc doesn't go into detail why it's not supported, but I suspect you are correct in that a DC has no local users.

Cheers,
