In GPay there is a score simulator to check change in cibil from account close.If your oldest credit card is more than 5 years old and second oldest credit card even if has an age of 1 year, closing the oldest credit card doesn't have any impact on CIBIL. Even after closing the oldest credit card, its payment record and card age will remain in CIBIL. I have already done this and have not seen even a single drop in CIBIL score.
