Hi Sujit ,
All the adjustments/reset after upgrade need to be take care in SPAU and SPDD .
SPAU - functions and reports .
Ones you go to SPAU , you would see all the reports ,function modules with traffic symbols and all the objects which need to be adjusted or reset .
You double click on the function module (not on the traffic signal) or report which you want to work on and it would take you into the object , there do a version comparision . You will find a button on the left side just above the code to see the differences between the versions . If you have to insert a code use insert using insert button on top or delete as needed and save
If you want to reset use reset to original .
let me know if its clear to you or not
Regards,
Bharathi
