Based on two-band Ginzburg-Landau theory, we study the upper critical fields for the overdoped composition of the iron-based superconductor Ba(Fe_{1-x}Ni_x)_2As_2 with x=0.072. All the temperature and angular results of this compound are consistent with the experimental data. Thus our analysis strongly suggests that Ba(Fe_{1-x}Ni_x)_2As_2 in the overdoped regime is a two-gap superconductor.
