Legacy Modernisation for HealthTech — UK Specifics
NHS HealthTech Legacy Platform Landscape
Common UK HealthTech legacy platforms requiring modernisation: (1) EMIS Health (GP clinical system — widely deployed, new EMIS API available but legacy integrations via HL7 v2.x), (2) SystmOne (The Phoenix Partnership — GP and secondary care system, REST API available), (3) Rio (community mental health — Servelec, now Civica), (4) Lorenzo (community and mental health — DXC Technology, CSC legacy), (5) RiO (Servelec community system), (6) legacy FHIR DSTU2/STU3 to R4 migration (NHS stopped R2/R3 support, R4 mandatory — significant NHS HealthTech upgrade requirement), (7) in-house PHP 5/7 custom clinical tools (built 2010–2018, pre-DTAC — highest modernisation risk).
FHIR Version Migration — STU3 to R4
NHS FHIR R4 migration from STU3/DSTU2: NHS Digital retired FHIR DSTU2 and STU3 support. All NHS integrations must now use FHIR R4 UK Core profiles. Migration complexity: (1) resource structure changes (Patient resource significantly changed R3→R4 — identifier slices, address format), (2) UK Core profiles (R4 has NHS-specific profiles not present in STU3 — UKCore-Patient, UKCore-Observation), (3) API version mismatch (HealthTech product may call STU3 API → NHS endpoint returns 410 Gone → product fails), (4) SNOMED CT binding changes (value set bindings changed R3→R4 — clinical coding values must be re-verified). Migration approach: map every FHIR resource in the legacy system → R4 equivalent → validate against HAPI FHIR UK Core profiles → test in NHS sandbox. ClickMasters FHIR R4 migration: 4 UK HealthTech products migrated from STU3.
DCB0129 During Legacy Modernisation
Legacy modernisation is a high DCB0129 risk — clinical functionality is being changed. DCB0129 requirements during modernisation: (1) clinical safety case review (existing clinical safety case must be updated to reflect architectural changes — not just the new features), (2) hazard transfer (hazards identified in legacy system: some resolved, some transferred, some new hazards introduced by modernisation), (3) parallel running clinical safety (during cutover: old system and new system both active — which system is clinically authoritative?), (4) rollback plan (if modernised system has clinical safety incident in first 30 days — tested rollback to legacy). ClickMasters DCB0129 modernisation: clinical safety case is a living document throughout the migration — not produced at the end.
NHS DTAC Reassessment After Legacy Modernisation
NHS DTAC for legacy HealthTech modernisation: if the product was previously DTAC-assessed, significant architectural change requires DTAC reassessment. DTAC change threshold: (1) new data flows (new personal data processed, new third-party integrations), (2) architecture change (monolith to microservices, on-premises to cloud), (3) new clinical functionality (new decision support, new AI). Re-assessment approach: (1) update Domain 1 data flow diagram (new architecture, new data flows), (2) new DPIA if new personal data processing, (3) new Domain 3 security assessment (new architecture = new attack surface), (4) Domain 4 interoperability update (new FHIR R4 integrations), (5) re-run WCAG audit (new UI components). ClickMasters DTAC reassessment: typically 6–10 weeks including evidence pack update and NHSX review.

Frequently Asked Questions
Common questions about healthtech software development.
How do we migrate a HealthTech product from FHIR STU3 to R4 without downtime?
FHIR STU3 to R4 migration with zero downtime: (1) build parallel R4 integration alongside existing STU3 (new endpoint, new FHIR R4 resources in parallel with STU3 — both active in staging), (2) validate R4 integration thoroughly (HAPI FHIR UK Core validator, NHS sandbox testing — all R4 resource types validated), (3) feature flag the R4 integration (95% of traffic to STU3, 5% to R4 — monitor for errors), (4) gradual traffic shift (5% → 25% → 50% → 100% R4 over 4 weeks — any R4 errors trigger rollback to STU3), (5) decommission STU3 only after 2 weeks of 100% R4 without errors. ClickMasters FHIR migration principle: STU3 stays alive until R4 is proven in production for 30 days. Delete STU3 only on day 31.
What is the cost of HealthTech FHIR R4 migration?
ClickMasters HealthTech FHIR R4 migration costs: (1) FHIR DSTU2/STU3 → R4 for a single NHS integration (e.g., PDS only): £8,000–£15,000 (4–8 weeks). (2) Full NHS integration stack migration (PDS + GP Connect + eRS + EPS — STU3 to R4): £30,000–£65,000 (14–22 weeks). (3) Legacy PHP HealthTech platform modernisation (complete rebuild with FHIR R4 from scratch — not migration): £60,000–£150,000 (24–48 weeks). (4) DTAC reassessment after migration: £5,000–£12,000 (6–10 weeks evidence update). All prices include NHS sandbox testing, HAPI FHIR UK Core validation, and DTAC evidence update. FHIR R4 migration is not optional — NHS Digital has phased out STU3 support.
