H1B Stamping Appointment on Old Employer pertition

Hi,

I have scheduled the H1B Stamping appointment with old employer details in visa scheduling website. However, I have moved to a new job. Can I use the same scheduled appointment?
I know I can take a new DS160 with new employer petition details, however, just concerned as I provided old employer petition details in the visa scheduling website while scheduling the appointment. Anyone in similar situation previously please help answer my question?
Thanks,

It just asked for petitioner name and validity right in and it did not ask for petitioner receipt number?
