Oh, so you are saying you wish to upgrade? Because Kotak doesn't allow more than one card. You'll have to try contacting customer care to see if you can be upgraded.

This was the only one I could find, but it is the generic MITC.
RBL guys when they gave me my World Supercard told me I will be eligible for World elite after a few months of using the card, possibly a hoax statement which they wont live up to :/
Card to card basis from your nearest branch would be the best bet. You will most possibly need a non-co-branded card with a high limit, preferably above 5L.
