Move-ADObject across domains for user?

Consulted Get-Help -ex for Move-ADObject and saw this:

Example 4: Move an object specified by distinguished name

This command moves an object with the distinguished name CN=Peter Bankov,OU=Accounting,DC=Fabrikam,DC=com to a different domain.

…but when I try it under Administrator prompt (Powershell 5) in the fabrikam root domain:

Move-ADObject -Identity “CN=EngineerUser,OU=Users,OU=Administrative Accounts,DC=canada,DC=fabrikam,DC=com” -server -Credential $creds -TargetPath “OU=destOU,DC=fabrikam,DC=com” -TargetServer

I get an error: Move-ADObject : The requested operation could not be performed because the directory service is not the master for that type of operation

What master? The RID Master?

Infrastructure master.

Thanks Dan
