Overview

Porting vs migration are both ways to switch your health insurance plan without losing continuity benefits like waiting period credits and no-claim bonus. The core difference is the provider. Health insurance porting means switching your policy to a new insurance company while carrying over your accumulated benefits. On the other hand, migration means upgrading or shifting to a different plan within the same insurance company. 

Both options are IRDAI-regulated and can only happen at renewal. Porting involves fresh underwriting by the new insurer. Migration is simpler, especially if you have been with that insurer for some years.

This guide is ideal for health insurance policyholders nearing renewal who are unhappy with their current plan or insurer and want to switch.

According to a 2024 BimaQuest study of 385 health insurance customers in Mumbai, the biggest reason people consider porting their health insurance policy is service quality. Other reasons include inadequate coverage, claim-related issues, the need for better customization, and premium concerns.

That tells us something important. Most people do not think about switching their health insurance policy when everything is going well. They think about it when something starts feeling wrong.

But in health insurance, “switching” can mean two very different things: porting and migration.

So, before you make the move, it is important to know which route actually fits your problem.

In this article, we will explain what porting and migration in health insurance mean, how the two differ, when each option makes sense, and how the process works step by step.

What Is Health Insurance Porting?

Health insurance portability lets you move your existing policy from one insurer to another, while preserving the continuity benefits you have already built up. Think of it like porting your SIM. You leave your current network provider but keep your phone number. Similarly, you leave your insurer but carry forward your waiting period credits, no-claim bonus, and moratorium years.

Basically, the core promise of porting health insurance is continuity. You do not start over. Your years already served count toward your new policy, up to your existing sum insured and eligible bonus.

This right is protected by IRDAI and is available to all individual and family floater indemnity health insurance policyholders.

Important: Porting is subject to fresh underwriting. The new insurer reviews your age, medical history, and claims record before deciding to accept, modify (with loading or exclusions), or reject your application.

What Is Health Insurance Migration?

Migration means moving from one health insurance plan to another within the same insurance company. Unlike porting, you are not changing the insurer. You are only changing the policy.

This Can Happen in Two Ways:

1. Voluntary Migration: This is when you choose to move to another plan offered by the same insurer because your current policy no longer fits your needs.

For example, let’s say you are happy with HDFC ERGO as an insurer, but your current plan, like Optima Restore, does not offer the benefits you now want. In that case, you may choose to migrate to a better HDFC ERGO plan, such as Optima Secure, at renewal, rather than porting out to another insurer.

2. Insurer-Led or Compulsory Migration: This happens when the insurer withdraws your existing product and offers you another suitable plan within its portfolio.

For example, when HDFC ERGO withdrew certain my Health Suraksha variants, existing policyholders were given the option to move to another HDFC ERGO plan, such as Optima Restore.

In both cases, migration helps you carry forward key continuity benefits, such as waiting-period credits and no-claim bonuses, subject to the applicable IRDAI rules and policy terms. This is important because you do not want to restart waiting periods from scratch just because you moved to another plan with the same insurer.

Migration can also have an underwriting advantage in some cases. If you have been continuously covered under an individual health insurance policy with the same insurer, migration may be allowed without fresh underwriting, but only up to the sum insured and benefits available under your previous policy.

However, this does not apply to every type of migration. For instance, if you are moving from a group health insurance policy, such as an employer-provided cover, to an individual policy with the same insurer, the insurer can still underwrite your application.

Did You Know?

Porting or migrating your health insurance policy does not come with a separate switching fee. As per IRDAI’s migration and portability guidelines, insurers cannot charge policyholders exclusively for migration or portability.

When Should You Port Your Health Insurance?

1) Systemic Claim Settlement Failures

If your insurer has unjustly rejected claims, made aggressive deductions from non-medical items, or repeatedly kept you waiting for cashless approvals, it can be frustrating. Porting to an insurer with a higher Claim Settlement Ratio (CSR) and a stronger operational reputation ensures your coverage actually works when a real emergency strikes.

2) Geographic Relocation or a Weak Local Network

Your health insurance is only as good as the hospitals where you can walk in and get treated without paying upfront. If you have moved to a new city or a tier-2 or tier-3 region where your current insurer has little to no footprint, your policy loses much of its utility. Porting lets you cross-verify and switch to a provider that dominates your new local healthcare ecosystem.

3) Unjustified Premium Hikes

Insurers occasionally revise pricing across product lines. But if yours has hiked your premium far above what the market charges for similar coverage, you are essentially paying a price penalty. Porting of health insurance policy lets you leverage market competition to secure comparable or better coverage at a normalized rate.

4) Outdated Policy Architecture

Older policies often come with restrictions such as room rent caps at 1% of the sum insured, mandatory co-payments, and narrow disease-wise sub-limits. If your current insurer does not offer modern plans internally with features like zero room rent limits and unlimited refills, porting lets you access a better plan without starting your waiting periods from scratch.

A Word of Caution

  • Do not port your health insurance policy just for a slightly lower premium or a minor feature upgrade. Switch only if the new policy offers a meaningful improvement.
  • Do not assume that full waiting-period credit will apply if you increase your sum insured while porting. The enhanced portion may come with fresh waiting periods.
  • Do not hide pre-existing diseases just because you had already declared them to your previous insurer. You must disclose them truthfully to the new insurer as well.
  • Do not cancel or let your existing policy lapse before the porting request is formally approved and the new policy is issued, as this can leave you without coverage.

When Should You Migrate Your Health Insurance?

Happy With the Insurer

If you are satisfied with your insurer’s claims experience, service quality, and hospital network, but not with your current plan, migrating can be a better option than porting.

High Underwriting Risk

If you have developed conditions like diabetes, hypertension, cardiac issues, or have a recent history of heavy claims, migration may be safer because a new insurer can reject or increase your premiums heavily on your porting request.

Four-Year Continuity

If you have been continuously covered with the same insurer for four or more years, migration may be smoother because the insurer already has your policy and risk history.

Individual to Floater

If your family's needs have changed, you may consider migrating from an individual policy to a family floater plan with the same insurer, subject to the insurer’s rules.

How to Port or Migrate Your Health Insurance: Step by Step

To Port Your Health Insurance Policy

    • Start 30 to 60 days before your renewal date.
    • Shortlist a new insurer and plan. Compare features, CSR, hospital network, exclusions, and waiting period terms.
    • Apply to the new insurer and complete their portability and proposal forms.
    • Submit your documents, such as current policy copy, last 2 to 3 years' policy documents, claim history, medical reports, and valid ID and address proof.
    • Your old insurer shares your policy and claim history with the new insurer via the IRDAI Insurance Information Bureau (IIB) portal.
    • The new insurer underwrites your case and communicates its decision within 5 days. If no decision is given in time, you can escalate your issue.
    • If approved, your new policy starts from your renewal date with all continuity benefits intact and no break in coverage.

To Migrate Your Health Insurance Policy

    • Contact your current insurer at least 30 days before your renewal date.
    • Request a migration to a specific plan within the same company and confirm which features differ.
    • Submit your existing policy documents, medical records, and ID proof.
    • The insurer issues the new policy (subject to underwriting) with all continuity benefits carried forward from day one.

Note: In both cases, keep all past claim records and policy documents safely stored, as they may be needed to cross-check details or support future claims.

Ditto's Take

The choice between porting and migration comes down to one question: Is your problem with the insurer or with the plan?

If the issue is with the insurer, such as repeated claim failures, a weak hospital network in your city, poor service, or pricing far above the market, porting may be the right move. 

But remember, while portability is an IRDAI-mandated right, insurers are often reluctant to accept porting cases. From their view, the risk is unclear. They have not collected premiums for the earlier years, but may have to cover claims immediately. Since most insurers prefer acquiring new customers and increasing penetration, they may make porting harder by stricter underwriting, raising minimum sum insured thresholds, mandating add-ons, increasing deductibles, or stricter eligibility rules.

If your issue is only with the plan’s features, try migration first. It is faster and lower-risk, and it may skip fresh underwriting if you have stayed with the same insurer for long enough.

Before you make any decision, pull up your insurer's CSR, Incurred Claims Ratio (ICR), complaint volumes, check their hospital network in your area, through Ditto’s Data Lab, and carefully read the waiting period terms of the plan you want to switch to.

Frequently Asked Questions

What is the difference between porting and migration in health insurance?

Porting vs migration comes down to who you switch to. Health insurance portability means you move to a new insurance company. Migration means switching plans while staying with your current insurer. Both are regulated by IRDAI. Both let you keep your waiting period credits (initial, specific illness, pre-existing disease, but not maternity) and no-claim bonus. Porting always needs fresh underwriting. Migration can skip this step if you have stayed with one insurer for. Evaluate your policy and situation before making any decision.

What is health insurance porting?

Porting health insurance policy lets you move to a new insurer. You do not lose the benefits you already earned. This includes your waiting period credits, no-claim bonus, and moratorium years. IRDAI protects this right for everyone with an individual or family floater plan. But porting is not automatic. The new insurer checks your age, your health history, and your past claims. They can accept your case, accept it with extra terms, or say no.

What is migration in health insurance?

Migration means you switch to a new plan with your same insurer. You do not change companies. It works in two ways. Voluntary migration is your choice, such as moving from Optima Restore to Optima Secure for better features. Compulsory migration happens when your insurer withdraws a product and offers you a new one instead. Either way, you keep your continuity benefits. In some cases, you skip fresh underwriting, too, as long as you have stayed with the same insurer for several years without a break in cover.

When should I port my health insurance policy?

Port your health insurance when the real problem is your insurer, not just your plan. At Ditto, we see four clear cases. Your claims keep getting rejected or delayed. You moved to a city where your insurer has weak hospital coverage. Your premium jumped far more than the market rate. Or your old plan still caps room rent at 1 percent of your sum insured. If none of this sounds like you, stay put. Long-term loyalty with one insurer often pays off more than a small upgrade.

When should I migrate my health insurance policy instead of porting?

Migrate when you like the insurer, but not your current plan. This often works better if your claims and hospital network have been smooth. It also helps if you have health issues like diabetes, since a new insurer may reject your port request or charge you more. Four or more years with the same insurer makes migration even easier, since they already know your risk profile. One exception: if you switch from a group health insurance plan to an individual plan, your insurer can still request fresh underwriting.

How many days before renewal can I port my health insurance policy?

Apply to port your health insurance 30 to 60 days before your renewal date. You can only port at renewal, never mid-term. Miss this window, and you have to wait for the next renewal cycle. Once you submit your documents, the new insurer must reply within 5 days. If they miss this window, the IRDAI rules state that your port gets approved automatically. Migration moves faster. You only need to contact your current insurer at least 30 days before renewal to ask for a plan change.

Can my health insurance porting request be rejected?

Yes, insurers can reject a porting request. This is because porting always involves fresh underwriting. You are an unknown risk to the new insurer. They check your age, health history, and past claims. Then they can accept you, accept you with some conditions, or say no. Common reasons for rejection include a poor claims record, hidden health issues, or missing documents. The good news is your old policy stays active if you get rejected, so your coverage never breaks.

Do I have to pay extra to port or migrate my health insurance policy?

No, you do not pay extra to port or migrate your policy. IRDAI's rules say insurers cannot charge a separate fee for either process. Your premium can still change, though. It depends on your age, your chosen sum insured, and how the new plan is priced. Some people end up paying less for similar cover. Others pay more if they pick a higher sum insured or add extra benefits to their new plan. Always compare quotes before you sign on for either switch.

Does my no-claim bonus get transferred when I port or migrate health insurance?

Yes, your no-claim bonus can be carried forward when you port or migrate your health insurance policy. But do not assume it will work exactly like it did in your old plan. The new insurer may adjust how the bonus is applied based on its own product rules. In some cases, the bonus may also help reduce waiting periods on the increased sum insured. Always check the final policy schedule to confirm how much bonus has actually been carried forward.

Does the moratorium period get transferred when I port or migrate health insurance?

Yes, the moratorium period already served under your old policy is carried forward when you port or migrate. It does not restart from zero just because you switched plans or insurers. For example, if you have already completed 3 years under your old policy, those 3 years should count in the new policy as well. But porting still requires fresh underwriting, so clearly disclose your medical history and keep old policy documents handy in case the insurer asks for proof.
