DCB Metal to Infinia upgrade plan

[airman]

Hi team,
I recently upgraded from a LTF Regalia (limit 4.5 lakhs) to FYF DCB Metal (limit 20 lakhs) in Feb '25. However, I am targeting an upgrade to Infinia. Not possible via the salary route.
For which I am planning to move some of my rent payments and my friends rent payments (~1.5 Lakhs per month total) to my Credit Card via Red-giraffe. Added on with some other personal expenses I am hoping to exceed 9 lakhs of spends in the next 6 months period.

Doubts -

1. Is there any cooldown period before I can ask for an upgrade, given that I was just upgraded recently?
2. If possible what are the chances for the upgrade, given that I would be paying quite a good sum for the surcharge charged by HDFC (1%+gst) and Redgirrafe for the rental payments. Would this be worth the trouble?
3. Would rent payments be fine to be counted as spends for the evaluation of the upgrade criteria?
4. Any other route that I can take?

1. Existing card which needs to be upgraded must be 6 months old.
2. No
3. Yes
4. Yes, If your existing salary is more than 5L/ month or your account has > 1 Cr deposits.

Upgrade is the most easiest and practical way possible.
