Multinucleon transfer reactions provide a possible access to the synthesis of new neutron-rich isotopes. Within the theoretical framework of a hybrid model combining the dinuclear system model and the GRAZING model together, the transfer reaction is investigated in $^{86}\mathrm{Kr}+^{248}\mathrm{Cm}$. In this work, it is found that the hybrid model can reproduce experimental transfer cross sections well. After the verification of the hybrid model, the transfer reactions $^{112,124,132}\mathrm{Sn}+^{249}\mathrm{Cf}$ are investigated by the influence of charge equilibration on the production cross sections of the exotic nuclei. The neutron-deficient projectile $^{112}\mathrm{Sn}$ shows advantages of producing neutron-deficient nuclei, while $^{124,132}\mathrm{Sn}$ are favorable to produce neutron-rich nuclei. In order to obtain available production cross sections of the unknown neutron-rich isotopes with $Z=99\text{\ensuremath{-}}102$, the dependence of cross sections on incident energy in the reaction $^{132}\mathrm{Sn}+^{249}\mathrm{Cf}$ is also investigated. It is found that the reaction $^{132}\mathrm{Sn}+^{249}\mathrm{Cf}$ at 510 MeV is a potential candidate to produce unknown neutron-rich isotopes of trans-target.
