The measurement of the $^{7}$Be(d,$^{3}$He)$^{6}$Li* transfer cross section at 5 MeV/u is carried out. The population of the 2.186 MeV excited state of $^{6}$Li in this reaction channel is observed for the first time. The experimental angular distributions have been analyzed in the finite range DWBA and coupled-channel frameworks. The effect of the $^{7}$Be(d,$^{3}$He)$^{6}$Li reaction on both the $^{6}$Li and $^{7}$Li abundances are investigated at the relevant big-bang nucleosynthesis energies. The excitation function is calculated by TALYS and normalized to the experimental data. The S factor of the (d,$^{3}$He) channel from the present work is about 50% lower than existing data at nearby energies. At big-bang energies, the S factor is about three orders of magnitude smaller than that of the () channel. The (d,$^{3}$He) reaction rate is found to have a less than 0.1% effect on the $^{6,7}$Li abundances.
