Healthcare Data Migration

Move the records. Keep their meaning and history.

Changing a platform means more than copying rows. We help healthcare teams define what moves, preserve source context and prove the migration against agreed completeness and workflow checks before cutover.

The workflow behind the interfaceScope → delivery
  1. 01
    Understand the source

    Inventory records, identifiers, attachments and historical meaning.

  2. 02
    Transform and reconcile

    Apply reviewed mappings, validate results and isolate exceptions.

  3. 03
    Rehearse and cut over

    Check the target workflow, agree the release decision and retain recovery options.

Find your starting point

What brought you here?

Explore a project situation to see the work, decisions and acceptance checks it could involve.

The starting point

Replace a legacy platform

The target model cannot represent every source field, and important decisions are hidden inside export scripts.

Inventory the source, classify mapping gaps and agree what is transformed, retained separately or excluded with a documented reason.

Illustrative project scenario—not a client case study.

Decisions we work through

  • Which records and date ranges are in scope?
  • How are unsupported fields and attachments retained?
  • Who approves clinical and operational equivalence?
Example acceptance check

The mapping register accounts for the agreed source fields and identifies every known exception or exclusion.

Implementation scope

Engineering work.
Reviewable outputs.

Define the workstreams and their acceptance criteria before delivery begins. Scope is tailored to your environment, access and operating model.

01

Source inventory and migration boundary

Identify datasets, formats, access limits, history, attachments and agreed exclusions.

02

Mapping and clinical context

Define identifiers, terminology, relationships, timestamps and provenance requirements for the target model.

03

Reconciliation and exception review

Compare agreed counts and relationships, validate sample workflows and track unresolved cases.

04

Rehearsal and cutover planning

Plan loading, catch-up, review gates, recovery limits and the post-cutover observation period.

A closer look at the handover

A migration should come with a reconciliation record

Sample review artefacts; acceptance criteria are agreed for the actual dataset and destination.

Example evidence and review structure
Area to reviewImplementation evidenceAcceptance consideration
Coverage reconciliationCompare source inventory with loaded, excluded and exception records.Differences are explained rather than hidden inside a total count.
Relationship validationTest the target links between representative patients, encounters and records.Broken or ambiguous references enter an exception report.
Workflow rehearsalReview migrated examples in the destination application.The responsible team records acceptance or the required correction.

Your deliverables use the requirements and acceptance criteria agreed for your project. This example does not imply certification, approval or completed testing.

Trust starts with clear boundaries

Know what we own.
And what needs your team.

This service is a controlled move between systems, not an open-ended analytics pipeline. Source access, retention policy, clinical acceptance and release authority stay explicit. We do not guarantee zero downtime, lossless conversion of unsupported fields or automatic clinical equivalence.

Before you commit

Answers for the
buying decision.

Is this the same as building a data pipeline?

A migration has a defined source-to-target transition and acceptance boundary. A recurring pipeline continuously moves or transforms data. A migration may need a temporary catch-up pipeline, but ongoing ingestion is scoped separately.

Can you migrate into a FHIR store?

Yes, subject to the source data and target capabilities. The work includes resource mapping, identifiers, profile validation, provenance and reconciliation—not only generating FHIR-shaped JSON.

Can you guarantee no downtime or no data loss?

No blanket guarantee is appropriate before assessment. We define the migration strategy, known limitations, validation evidence and recovery boundary for the systems involved, and identify the residual risks for review.

Who decides what happens to the old system?

Your authorized stakeholders decide retention, access and decommissioning based on operational, contractual and applicable requirements. We provide the technical inventory and migration evidence to support that decision.
