I tried the swipeUp program today
first after giving mobile no and PAN they verified by OTP
then in next stage Aadhaar verification happened via OTP
after that there is option to give first 6 digits of your existing card and then they're showing the xcite card options in a comparative view with current card and to proceed then along with a back option if you want to change
I didn't proceed and always used back because they never showed me the Xcite only card itself
out of my 9 cards, for 4 I got Ultra option, for 3 got Ace option, and the other 2 wasn't recognized as not present in their current database
got choice of Ultra for Regalia, IDFC Select, Citi Rewards and MRCC
Ace was given choice for Axis Flipkart, ICICI Amazon, RBL Zomato
HSBC Platinum & SBI Tata Titanium wasn't recognized
