In both source and target domains :

You also need to create a local domain group in the source domain called “SourceDomain$$$” where SourceDomain is the NetBios source domain name.

ADMT Prerequisites : Permissions

Migrate SID Hstory

To perform an Active Directory migration without any disruption for your users, you may need to migrate the SID of the user in the old domain in the SidHistory of the user in the new domain. To do that, you need the permission called “Migrate Sid History“, you apply that at the domain level.

Administrative Privileges on the source

You also need some administrative privileges on the source domain. The easiest way is to put the account initiating the migration into the “Administrators” group in the source domain.

You also need an Active Directory trust between the two domains.
