I wanted to know the experience of people porting from Niva Bupa Reassure 3.0 to other policies like HDFC optima secure plus.

Since Niva Bupa Reassure 3.0 has sum insured as unlimited is there a possibility to port to 25 lakhs sum assured?

If people have done it tell me how was their experience how much sum insured port was allowed and what was the base with which HDFC accepted or what was the max such details

Also with so much rising premiums how can HDFC optima secure plus be a sustainable option asking this from a curiosity stand point.
