Work visa (z) to Student type (x)

I have switched my working type (Z) to student (X1) type from my country but I still have the resident permit of Shanghai (my working place) but now with the X1 type i have to go to Beijing to do my Phd. But for the clearance purpose my company is asking me to do the following steps:

1. The procedure for cancellation of Work Permit
Documents to submit (5 working days to process)
a. application to cancel work permit for foreign nationals (signature required)
b. The original Work Permit
2. The procedure for cancellation of Working Visa
Documents to submit (at least 7 working days to process)
a. Passport (passport will be returned after completion-at least 7 days)
b. 1 copy 2 inches colour photo
c. Temporary residency certificate (临时住宿证明)-original & photocopy
but as i know when i apply for student type my work type gets canceled automatically.
In this case do I have to follow those procedures.
Please advise me...
