How to update my roster from 2k17 to 2k18 roster in NBA 2k17?

Please help me to do updating my roster in 2k17 to 2k18 rosters that will appear also in my career offline thanks.

Just load an updated roster in the edit player menu. Then use limnono trainer F10 copy roster. Now back out of edit roster and start a new mycareer. Now you will have Mycareer with updated roster. Close limnono trainer and enjoy
