Customer success story
The University Hospitals Sussex NHS Foundation Trust unified regional healthcare data
Cloud database migration accelerated UHSussex’s system scalability.
Pythian executed a zero-downtime migration of UHSussex's core database, analytics, and financial planning systems to Oracle Cloud Infrastructure.
Faced with an impending regional trust merger handling 1.5 million annual patient visits alongside expensive, end-of-support legacy reporting platforms, UHSussex needed a scalable cloud architecture to reduce operating costs and unify regional data. Pythian synchronized deployment schedules with a third-party Oracle EBS Cloud vendor, exporting on-premises databases to Oracle Autonomous Data Warehouse (ADW), mapping Oracle Data Integrator (ODI) workflows, refactoring Oracle Analytics Cloud (OAC), and deploying Oracle Enterprise Planning and Budgeting Cloud Service (EPBCS). Upgrading Autonomous Data Warehouse to Oracle Database 23ai eliminated tedious routine maintenance, guaranteeing uninterrupted patient care during the transition and putting instant, AI-powered medical insights directly into clinicians' hands across all merged hospitals.
They had previously been supporting Brighton & Sussex University Hospitals with our on-premises versions of OBIEE & Hyperion. An experienced and knowledgeable provider was required to help us convert these applications to the latest cloud versions while the merger of two trusts, Brighton & Sussex University Hospitals and Western Sussex Hospitals took place. The merger also involved upgrading to one financial general ledger on Oracle EBS Cloud 12.2 which was undertaken by a third party.”

New trust users onboarded rapidly post-merger
Modernize enterprise Oracle database infrastructure to accelerate scale.
End-of-support legacy platforms threatened reporting continuity across 1.5 million annual patient visits after the merger.
Pythian exported on-premises databases directly to Oracle ADW and refactored core reporting workloads with zero operational downtime.
They lived up to and exceeded expectations with the upgrade to the cloud versions of OAC & PBCS, as well as helped us gain some critical insights about the Oracle EBS migration as we were working to a very tight timeline."

Legacy reporting platforms increased operating expenses
Outdated on-premises OBIEE and Hyperion systems created unsustainable maintenance overhead and operational risk for the growing trust.
Trust merger demanded immediate multi-region scaling
Combining two healthcare trusts required rapid onboarding of 1,000 new users while synchronizing data releases with a third-party Oracle EBS Cloud migration.
Fragmented data restricted self-service analytics
Separate legacy systems prevented cross-trust data alignment, slowing down financial planning and critical reporting processes.
High patient volumes required zero cutover downtime
Handling 1.5 million annual outpatient, A&E, and surgery cases meant system downtime during migration was completely unacceptable.
Migrated on-premises databases to Oracle ADW and upgraded to Oracle Database 23ai with zero operational downtime.
Pythian exported legacy databases directly to Oracle ADW using pre-tested scripts without interrupting patient care. The system was later upgraded to Oracle Database 23ai to add automated tuning and AI features. This cut manual maintenance and keeps data synced across all systems.
Replaced OBIEE with Oracle Analytics Cloud to deliver self-service data visualization.
Oracle Database Engineers converted the legacy OBIEE reporting system into Oracle Analytics Cloud (OAC). Automated testing checked data models before launch so teams got faster reports. Staff now share one clean source of data and create visual reports on demand.
Accelerated financial consolidation cycles and streamlined cross-trust budgeting.
Our Consultants replaced legacy Hyperion with Oracle EPBCS configured with a dual BSO/ASO architecture. Experts set up this optimized configuration to boost processing speeds during complex financial reviews across hospital sites. As a result, healthcare leaders gained real-time financial visibility while empowering finance teams to manage multi-region budgets efficiently.
Synchronized third-party releases and provided hands-on staff training.
Pythian Engineers mapped Oracle Data Integrator (ODI) workflows early against the third-party EBS Cloud system to stay ready for launch. Automated tests built team confidence and speeded up approvals. Custom training and ongoing technical support gave staff total control over daily workflows.
