  In this paper we study integrability and non-integrability for type-IIA
supergravity background dual to deformed plane wave matrix model. From the bulk
perspective, we estimate various chaos indicators that clearly shows chaotic
string dynamics in the limit of small value of the parameter $L$ present in the
theory. On the other hand, the string dynamics exhibits a non-chaotic motion
for the large value of the parameter $L$ and therefore presumably an underlying
integrable structure. Our findings reveals that the parameter $L$ in the
type-IIA background acts as an interpolation between a non-integrable theory to
an integrable theory in dual SCFTs.
