In this paper, the non-Markovian dynamics of a coupled $N$-cavity model is studied based on the quantum state diffusion (QSD) approach. The time-local Di\'{o}si-Gisin-Strunz equation and the corresponding master equation are derived for a coupled cavity array. Non-Markovian effects are studied in two examples, two-cavity and three-cavity, under different boundary conditions. We have shown that the environment-memory can facilitate the cat-like state transfer from one cavity to another in the case of a strongly non-Markovian environment. We show that the non-Markovian QSD approach can be a valuable tool for the dynamics of a multi-partite continuous-variable (CV) system.
