Purpose-built ETL platform for Epic Systems to Oracle Fusion migration of the downstream finance, HCM and SCM stack. Clarity-certified extractors, Cogito-grade reconciliation, FBDI/HDL emission. Chronicles and EpicCare remain untouched as your system of record for clinical.
Epic is the #1 US EHR and stays the system of record. The epic systems to oracle fusion migration consolidates the downstream business stack — never the clinical record.
Epic Systems, headquartered in Verona Wisconsin, powers more than 30% of US hospital beds and the majority of academic medical centres. Chronicles, the InterSystems Caché/IRIS MUMPS hierarchical database, holds the operational EHR. Clarity, the relational SQL Server mirror, serves reporting. Cogito provides analytics. EpicCare runs the clinical workflow, Hyperspace serves the desktop UI, MyChart serves patients. None of that moves to Fusion.
What does move to Oracle Fusion in an epic systems to oracle fusion migration is the back office: the general ledger (often still on Lawson, PeopleSoft or ageing on-prem EBS); accounts payable; fixed assets; supply chain and materials (often a mix of McKesson, Premier and home-grown); HCM and payroll (often Lawson HR); and the financial reporting layer that has to consume Epic Resolute Hospital Billing and Professional Billing journal feeds.
The architecture: Epic remains the unmodified clinical system. Resolute keeps generating AR sub-ledger journal entries. Willow keeps tracking pharmacy inventory. OpTime keeps logging surgical case-cart consumption. Each of those generates a downstream feed — and each feed becomes either a one-time migration payload or a steady-state Oracle Integration Cloud flow into Fusion. Syntra ETL builds both, with Clarity-certified analysts on the Epic side and FBDI/HDL specialists on the Fusion side.
And how the Syntra ETL platform handles each — without ever touching the clinical record.
EpicCare, Chronicles and MyChart remain the system of record. Zero changes to clinical configuration. Migration scope is strictly downstream finance, HCM and SCM — the modernization story without the clinical risk.
All read happens from Clarity (SQL Server relational mirror) and Cogito (analytics layer) using Clarity-certified analysts. Chronicles MUMPS is never touched directly — preserves Epic warranty and support model.
Resolute Hospital Billing and Professional Billing keep producing AR sub-ledger journals. We migrate the journal posting feed pattern, not the billing engine. Patient AR aging stays where clinicians expect it.
Steady-state integration through Oracle Integration Cloud using HL7 v2 messages, FHIR R4 APIs and Interconnect web services. Willow → Fusion Inventory, OpTime → Fusion Materials, Beaker → Fusion Cost Accounting.
PHI never leaves your authorized boundary. Every extract, transform and load step is HIPAA-logged. Audit trail satisfies 42 CFR Part 2, HIPAA Privacy Rule and state retention rules 5–30+ years.
Common 2025–26 pattern: Epic clinical + legacy Cerner financials consolidating to Fusion after Oracle's 2022 acquisition. The epic systems to oracle fusion migration plays into this — replacing Cerner Millennium ERP feeds with Fusion.
A repeatable, governed workflow built for the realities of a health system. Typical regional system timeline: 16–24 weeks. Epic clinical operations are unaffected throughout.
Discovery engine inventories Clarity tables, Cogito models, Resolute HB/PB configurations, downstream interfaces, current legacy finance/HCM/SCM systems. Output: scope map, source-system retirement plan, Epic interface inventory, sized assessment with HIPAA risk register.
COA design (typically 7 segments for healthcare: Entity, Service Area, Department, Account, Cost Center, Patient Type, Future), worker master mapping, Resolute → Fusion GL journal posting design, OIC interface architecture for Willow/OpTime/Beaker steady-state feeds.
Clarity extractors pull AR aging, GL trial balance, worker master, payroll history, supplier master, materials transactions, fixed assets. Reconciled against Cogito at row, sum and hash level. Staged as Parquet with hash-signed manifests, partitioned by fiscal period and service area.
Crosswalks applied: Lawson account → Fusion COA, McKesson supplier ID → Fusion Supplier Number, Resolute journal pattern → Fusion GL. FBDI Journal/Invoice/Supplier templates emitted, HDL Worker.dat for HCM. Errors surfaced locally with row-level diagnostics — not in a 4-hour Fusion ESS job.
FBDI ZIPs submitted to Fusion ESS, monitored to completion, reconciled at row, sum and hash level. In parallel, OIC integrations built for steady-state Willow/OpTime/Beaker feeds. HL7 v2 inbound, FHIR R4 outbound where applicable. Critical OTBI dashboards rebuilt from Cogito equivalents.
1–2 month-end close cycles in parallel (legacy + Fusion), Resolute downstream journals running into Fusion via the new feed, deltas captured and replayed. Sign-off pack issued to CFO, controller and internal audit. Legacy ERPs cut to read-only archive; Epic continues unaffected.
Clarity-certified extractors covering the downstream finance, HCM and SCM domains. Chronicles is never accessed directly.
Hospital and Professional Billing AR sub-ledger journals via Clarity ARPB_TRANSACTIONS, HSP_TRANSACTIONS and HSP_ACCOUNT. Period-summarised, COA-mapped, FBDI Journal Import ready.
Multi-year GL trial balance for legacy ledger (Lawson, PeopleSoft, EBS, McKesson), reconciled against Cogito and routed to Fusion GL via FBDI Journal Import as opening balances + history.
CLARITY_EMP, CLARITY_SER provider/staff master, plus payroll history from the legacy HRIS (Lawson, PeopleSoft) — converted to HDL Worker.dat for Fusion HCM Core HR load.
Pharmacy inventory transactions, dispensing history, formulary master from Willow via Clarity. Migrated as Fusion Inventory items + transactions; steady-state continues via OIC + HL7 MFN messages.
Surgical case-cart material consumption, preference cards, implant tracking from OpTime via Clarity. Routed to Fusion Inventory + Cost Accounting; steady-state through Interconnect + FHIR Resource APIs.
Lab reagent consumption, supplier purchase history, instrument-linked materials from Beaker via Clarity. Migrated as Fusion Inventory + Procurement supplier master.
Important framing first: Epic Systems is the clinical system of record. An Epic Systems to Oracle Fusion migration does NOT replace EpicCare, Hyperspace, Chronicles or MyChart — those stay. What moves to Oracle Fusion is the downstream finance, HCM and supply chain stack: GL, AP, AR, fixed assets, procurement, employee master, payroll-feed accounting and materials management. The work is to extract the Clarity reporting database (the SQL Server mirror of Chronicles), reconcile against Chronicles via Cogito, route finance and HCM data into Fusion via FBDI/HDL, and leave Epic in place as the authoritative clinical platform with Fusion as the new ERP/HCM. Typical timeline: 16–24 weeks for a regional health system.
Three converging drivers. First, Oracle's $28B Cerner acquisition (2022) reshaped the healthcare ERP market — many Epic-clinical, Cerner-financial sites are consolidating onto Fusion. Second, legacy ERPs alongside Epic (Lawson S3, PeopleSoft, McKesson finance, ageing on-prem EBS) are hitting end-of-life or sustaining-only support. Third, the Epic Resolute Hospital Billing and Professional Billing modules feed revenue into a general ledger that increasingly needs cloud-native consolidation, IFRS 17 / GASB reporting, and AI-assisted close. An Epic Systems to Oracle Fusion migration consolidates the back-office around Fusion while leaving Epic clinical untouched — the most common pattern we see in 2025–26 health system roadmaps.
No. Chronicles is the InterSystems Caché/IRIS MUMPS hierarchical database that powers Epic's transactional EHR — we never write to it, we never restructure it, we don't introduce risk into the clinical record. All extraction happens from Clarity (the SQL Server relational mirror) and from Cogito (Epic's analytics layer). For real-time integration scenarios we use Epic's published interfaces: HL7 v2 messages, FHIR R4 APIs, and the Interconnect web-services framework. Epic remains the unmodified system of record. The Epic Systems to Oracle Fusion migration only touches finance/HCM/SCM data that is leaving Epic's downstream feeds and landing in Fusion.
Yes — on the Epic-side extraction work we require Clarity-certified analysts (Clarity Data Model proficiency, Cogito certification) for the read-side, and your existing Epic technical team for any net-new interface work (Bridges, Interconnect). Syntra ETL provides the Fusion-side: FBDI/HDL specialists, OIC integration architects, reconciliation engineers and migration PMs. We do NOT touch Epic Chronicles configuration, EpicCare workflow or Hyperspace builds — those are protected operational changes that go through your Epic governance. The blended team typically includes 4–6 Epic Clarity analysts (yours), 8–12 Syntra ETL Fusion engineers, plus your clinical informatics representatives signing off on every downstream change.
Resolute HB and PB generate the AR sub-ledger that ultimately posts to the general ledger. During an Epic Systems to Oracle Fusion migration we keep Resolute as the system of record for charge capture, claim production, patient billing and contractual adjustments — it stays in Epic. What we migrate is the summarised GL journal posting: Resolute generates a journal entry batch, that batch is extracted via Clarity, mapped to the new Fusion COA (typically a 7-segment chart for healthcare), and posted into Fusion GL via FBDI Journal Import. AR aging stays in Resolute; what Fusion sees is the consolidated AR balance per service area. This preserves Epic's revenue cycle while modernising the close.
Yes. OpTime (surgical), Willow (pharmacy inventory), Beaker (laboratory), Stork (obstetrics), ASAP (emergency) — all the clinical and ancillary modules stay in Epic as the system of record. Only their downstream supply chain feeds touch Fusion: Willow's pharmacy inventory consumption feeds Fusion Inventory and Cost Accounting; OpTime's case-cart material usage feeds Fusion SCM Materials Management; Beaker's reagent consumption feeds Fusion Inventory. The Epic Systems to Oracle Fusion migration sets up these feeds as interface points (typically HL7 MFN/MDM or FHIR Resource APIs through Interconnect into OIC), not as data migrations. Epic stays clinical; Fusion becomes the materials and cost system.
Every Epic source extract is reconciled at three levels before it loads to Fusion. Level one: Clarity row-count vs Chronicles row-count via Cogito (catches Clarity ETL lag). Level two: Clarity sum totals vs Cogito sum totals per period per service area (catches in-period adjustments). Level three: post-load Fusion GL balance vs Epic Resolute AR balance vs Cogito period-end snapshot (catches transformation errors). Output is a signed evidence pack per fiscal period covering all three reconciliation tiers. For a 5-hospital system this typically produces 100–200 reconciliation artefacts per month-end during parallel run, all hash-signed and stored for SOX and Joint Commission audit retrieval.
For a regional health system (3–8 hospitals, 200–800 beds each, ambulatory networks attached) running Epic clinical + legacy finance: 16–24 weeks for the Fusion finance and HCM cutover, plus 6–10 additional weeks for SCM, materials, and full integration hardening. Larger academic medical centres (15+ hospitals, multiple instance consolidation) run 9–14 months. The Epic side is unaffected throughout — there is no Epic upgrade, no Epic downtime, no Epic configuration change required. Syntra ETL's pre-built Clarity extractors, Cogito reconciliation harness and Fusion FBDI templates compress the timeline by 40–55% versus a consultant-led Epic Systems to Oracle Fusion migration.
