Conversion witness provides a way to detect possible state transformation without computing monotone. The idea is a generalization to the idea of entanglement monotone. Recently, in New.J.Phys. \textbf{17}(2015) 093013 Girard et.al., have computed the form of conversion witness. We have extended the computational technique to cover more general orthogonally invariant class of states and compute the form of conversion witness. In this lecture, we will provide  few examples regarding state conversion using the new class of witnesses.
