Great News guys -
Old card milestone benefit also transferred to new Millennia RuPay -
Milestone gv did not came automatically after conversion, like usually we get within 2-3 days earlier on visa. Only after sending emails, they sent the gv
Today, one guy share this info -
i sent email to HDFC and after 2-3 to-fro emails, today they sent email for 1 lakh milestone gv(however getting error to redeem. Will try again in 1-2 days).
86k was spent on old visa and 14k spent on new rupay millennia. So they considered old spent too for quartly milestone.
Hope this helps many.
