One of the user groups that is created in the ControlPoint Configuration Site when ControlPoint is first installed allows farms with different service accounts to authorize with each other when a cross-farm copy or move is performed.
The default name that ControlPoint assigns to this group is Remote Service Account Administrators. Because of special configuration requirements, if a different name is assigned to this group then the ControlPoint Application Administrator must update the Value of the ControlPoint Setting Remote Service Account Administrators for Cross Farm Operations with the new name so that ControlPoint will continue to recognize it.
