This is from the perspective of a TClientDataset derivative.

procedure TMyClientDataset.CopyFromDatasetProvider(Dataset: TDataset);
 var DataSetProvider : TDataSetProvider;
begin
  DataSetProvider := nil;
  try
    Close;
    DataSetProvider := TDataSetProvider.Create(nil);
    DatasetProvider.Options := [poNoReset];
    StoreDefs := False;
    DataSetProvider.DataSet := Dataset;
    SetProvider(DataSetProvider);
    Open;
    First;
    SetProvider(nil);
   finally
    if Assigned(DataSetProvider)
     then DataSetProvider.Free;
   end;

end;

Drop a TDataSetProvider onto the form or datamodule with the ClientDataSet, set the ClientDataSets property ProviderName to the name of the TDataSetProvider. Set the DataSet property of the TDataSetProvider to the other dataset. Open the ClientDataSet.
