Pharma and life sciences organizations are racing to modernize their IT ecosystems, yet legacy systems continue to weigh them down. From LIMS (Laboratory Information Management Systems) to pharmacovigilance platforms, these critical systems hold decades of institutional knowledge but often rigid, expensive, and non-compliant with today’s digital-first environment
Pharma and life sciences industry face constant pressure to accelerate innovation, maintain regulatory compliance, and reduce operational costs while managing complex IT ecosystems that have evolved over decades. A critical challenge many organizations face today is legacy system migration and code verification. They still depend on custom-built systems that manage essential workflows such as clinical data, laboratory processes, regulatory submissions, and pharmacovigilance reporting.
Modernizing these systems is more than a lift-and-shift exercise. It demands re-automation of processes, verification of migrated logic, and adherence to standards like 21 CFR Part 11, GxP, and GDPR. Generative AI (GenAI) is emerging as a powerful tool to simplify and speed up this transformation.
Legacy migration in regulated industries carries multiple risks and constraints. Below are common challenges that organizations face:
Cost and time pressure: Traditional migration projects often stretch over several years, demanding significant investments and carrying high risk of error or non-compliance.
These challenges make automation and verification critical to any modernization effort.
GenAI introduces intelligence and adaptability into the migration process. It enables re-automation by intelligently mapping, modernizing, and validating processes with minimal manual intervention.
Below are key areas where it can bring tangible impact:
GenAI can analyze legacy code, interpret business logic, and generate modern equivalents in frameworks such as Python, Java, or cloud-native architectures. This eliminates manual re-coding and reduces the risk of missed logic.
In regulated pharma environments, test scripts and validation protocols must be traceable and exhaustive. GenAI can automatically generate unit tests, integration tests, and compliance checklists from existing specifications to accelerate validation cycles and maintain auditability.
AI-driven verification tools can detect anomalies, redundancies, and potential compliance gaps. For instance, if a pharmacovigilance migration alters data reporting logic, GenAI can flag the discrepancies before deployment and reduce the risk of non-compliance.
Scientists and business users can describe workflows in plain English (e.g., “extract adverse event reports by region and classify severity”), and GenAI can translate that into executable queries or scripts.
Standard Operating Procedures (SOPs) that exist in static documents can be transformed into digital workflows. GenAI can analyze documentation, identify procedural gaps, and propose digital SOPs aligned with Good Automated Manufacturing Practice (GAMP 5) standards.
When Pharma and Life Sciences organizations adopt GenAI in migration, they realize multiple advantages:
Scalable innovation: Modernized platforms integrate seamlessly with cloud, AI-driven analytics, IoT, and digital twin technologies for next-gen R&D
Below are illustrative scenarios where GenAI-driven re-automation is already making a difference:
Re-automating safety database migration with AI-backed validation ensures consistency and compliance with MedDRA standards.
Migrating legacy SAS-based trial repositories to cloud-native architecture, with GenAI verifying data logic and lineage.
Upgrading on-premises systems to AI-enabled, cloud workflows while automating lab processes and validations.
Automating eCTD (Electronic Common Technical Document) data validation and version control during migration to ensure consistency and audit readiness.
These use cases show how GenAI supports both technical transformation and regulatory demands.
Pharma and life sciences organizations must treat re-automation as central to legacy migration and not an add-on. GenAI helps translate old logic into modern platforms, verify correctness, and maintain compliance.
At Accion Labs, our experience applying AI and cloud solutions in regulated settings has shown that success depends on a phased approach, clear governance, and close alignment with business needs. We assist clients in defining strategy, piloting use cases, and scaling up migration efforts while preserving regulatory integrity.
