An AI-driven modernisation of a legacy on-premises Oracle estate — migrated to Oracle multi-cloud on AWS, with a purpose-built AI tool extracting decades of embedded PL/SQL business logic into independent microservices.
The client ran a business-critical on-premises Oracle database that had accumulated over a decade of embedded business logic inside PL/SQL packages, procedures, and triggers. That logic was tightly coupled to the database, poorly documented, and effectively unreadable without deep institutional knowledge — making cloud migration or any kind of modernisation high-risk. A manual rewrite was estimated to take years and risked silently breaking business rules nobody had fully documented.
Algorex designed an AI-driven modernisation pipeline that migrated the database and made the hidden business logic visible, testable, and portable for the first time.
Moved the database to Oracle multi-cloud on AWS, preserving full Oracle compatibility while gaining managed operations, elasticity, and disaster recovery.
A custom-built tool that parses stored procedures, functions, and triggers to identify and document embedded business logic automatically.
Automatic mapping of relationships between procedures, tables, and triggers that had never been formally documented.
Extracted logic used to auto-generate service boundaries and scaffolding, turning monolithic procedures into testable, deployable microservices.
Automatically generated tests to verify migrated logic behaves identically to the original stored procedures.
Designed for resilience and flexibility rather than single-vendor lock-in.
