The Data Migration Architect is responsible for defining and governing the safe migration of clinical data from the legacy DMICP estate into target systems such as TPP SystmOne and downstream consumers via HealthShare. This is a design‑led role that sets the rules, frameworks, and standards for migration-while engineers carry out the technical delivery. The architect ensures that all migrated data is accurate, clinically safe, auditable, and aligned to programme constraints.
What You'll Be Doing
Defining the end‑to‑end migration strategy, including scope, sequencing, and success criteria.
Determining which data is migrated, archived, or excluded, ensuring alignment with clinical safety and governance.
Validating findings from analysts (profiling, data quality, code‑mapping impacts) and identifying migration risks.
Owning the Data Migration Architecture, including source, staging, and target data models.
Producing clear design artefacts: logical mappings, cleansing/validation rules, exception handling, and cutover patterns.
Providing architectural oversight to migration engineers and resolving design issues during build.
Approving execution plans and ensuring reconciliation, verification, and auditability for rehearsal and live runs.
Supporting post‑migration assurance and contributing to improvements for future migration waves.
What We're Looking For
Proven experience as a Data Migration Architect in large, complex data programmes.
Strong understanding of clinical or regulated data migration, including legacy‑system challenges.
Knowledge of clinical coding standards such as READ, SNOMED, and dm+d.
Ability to produce clear, authoritative migration designs and operate as a design authority.
Excellent communication skills and stakeholder engagement capability.
(Desirable) Experience with EHR systems such as TPP SystmOne or EMIS.
(Desirable) Experience working with clinical safety, audit, and governance requirements.
(Desirable) Experience designing phased, delta or dual‑running migration models.
