Yes. The Insurance Regulatory and Development Authority (IRDA) has issued a circular making it effective from 1st October, 2011, which directs the insurance companies to allow portability from one insurance company to another and from one plan to another, without making the insured to lose the renewal credits for pre-existing conditions, enjoyed in the previous policy. However, this credit will be limited to the Sum Insured (including Bonus) under previous policy. For details, you may check with the insurance company.
