How to upgrade from Normal to Premium Service for UK Visas

Question

As per the recent suspension of biometrics enrolment for UK visas at US Application Support Centres, I wanted to upgrade from normal to premium service to use the New York Premium Application Centre. Do I have to cancel my current appointment to do that? As far as I understand, I have to cancel my current application and submit a new one, including the questionnaire.

EDIT: I was scheduled to go to ASC on Apr 17th, went straight to the Premium Centre instead, did not pay or upgrade or anything. They admitted me even though my supposed rescheduled date was Apr 26th. Got lucky I suppose. Proceed with caution.

Answer 1

Officially yes, once you've booked your appointment you are meant to cancel your normal application and rebook a premium one to upgrade as stated on the vfs website:

Please note: once you have selected the type of centre to attend for your biometric appointment on GOV.UK, you will not be able to alter your selection without cancelling your application and starting a new one.
