Migrating From One Health App to Another: What Actually Transfers
A health app might be excellent for three years and stop being the right choice — features change, pricing shifts, ownership moves, better options appear. Moving to a different app is a real option, but only if the data comes with you. Understanding what transfers cleanly, what transfers imperfectly, and what does not transfer at all is what determines whether the migration is a weekend project or a data-loss event.
What usually transfers cleanly
- Data type: PDF documents (prescriptions, reports) · Transferability: Excellent — universal format
- Data type: Photographs (uploaded images) · Transferability: Excellent
- Data type: DICOM imaging · Transferability: Good if the new app supports it
- Data type: Basic member info (name, DOB, blood group) · Transferability: Good
- Data type: Structured medicine list · Transferability: Moderate — depends on both apps' schemas
- Data type: Allergy list · Transferability: Moderate — severity may not transfer
- Data type: Encounter/visit dates · Transferability: Moderate
- Data type: Extracted lab values · Transferability: Variable — depends on structure alignment
- Data type: Trend graphs · Transferability: Poor — usually regenerated by new app from source values
- Data type: Sharing history and active grants · Transferability: Very poor — usually reset
The FHIR promise
The healthcare data standard FHIR (Fast Healthcare Interoperability Resources) is designed to make this transfer better. In principle, a FHIR-compliant export from one app should import cleanly into another FHIR-compliant app.
In practice, as of late 2025, FHIR adoption in Indian consumer health apps is patchy. Some export FHIR; some import it; the ones that do both cleanly are still few. If migration might be in your future, an app that offers FHIR export is a stronger long-term choice.
The step-by-step migration
- Step 1: Export everything from the old app. Save the export somewhere safe (external drive + cloud).
- Step 2: Verify the export — unzip and check that files are there and readable.
- Step 3: Install the new app and set up accounts.
- Step 4: Add family members and basic info manually if needed.
- Step 5: Import the documents (usually category by category — prescriptions, then lab reports, then discharge summaries).
- Step 6: Manually re-add current medicines, allergies, and any structured data that did not transfer.
- Step 7: Test — can you find a specific old document? Is the family view working?
- Step 8: Only after everything is working, close the old app account.
What to expect in the imperfect transfer
Realistic expectations for what will require manual re-entry:
- Current medicines list — spend an hour re-entering with current doses and prescribers.
- Allergy severity ratings.
- Recent trend markers that had been auto-populated (last few HbA1c values, etc.).
- Care team list — doctor names, phone numbers, next appointment dates.
- Any custom tags or categorisations you had built up over years.
- Alert rules — will need to be re-set in the new app.
The old-app closure — do it deliberately
Once the new app has everything, close the old:
- Request account deletion, not just uninstall the app.
- Confirm the provider has deleted your data — a written confirmation is worth asking for.
- Under India's DPDP, you have a right to deletion. Exercise it.
- Keep the export file as backup for at least a year in case any data was missed.
The signals that it might be time to migrate
Not every dissatisfaction warrants migration. Real signals:
- The provider is unresponsive to bugs or user requests over months.
- Pricing has shifted significantly in an unfavourable direction.
- New features you need are not available and not on the roadmap.
- The provider is being acquired or announcing structural changes.
- A significantly better alternative exists — not marginally, but noticeably.
Migration is real work. It should be justified. A dissatisfaction that could be addressed with a settings change or a feature request often does not warrant it.
