How a leading UK insurance group created a repeatable, scalable approach to complex PAS migration
the challenge
A leading insurance group was operating across more than 20 policy administration systems, each with its own workflows, data structures and ways of working.
As the business evolved, that complexity made change harder, increased maintenance costs and created inconsistency across teams and customer journeys.
The organisation needed to simplify its estate and create a cleaner route to future consolidation, while maintaining data quality and reducing the burden of manual migration activity.
the solution
Dufrain helped turn a complex migration challenge into a repeatable delivery approach.
The work began with data analysis and planning, before building a transformation engine to automate cleansing, transformation and validation throughout the ETL process.
This reduced reliance on manual effort and created greater consistency across each migration.
The approach also enabled migrations to run concurrently and supported knowledge transfer into the internal team, helping create a scalable model that could be used across future consolidation activity.
the outcome
The programme created a more repeatable and scalable approach to PAS migration, enabling the business to move significant volumes of complex data while protecting quality.
Key outcomes included:
- 20M+ data records migrated
- 300+ fields mapped, transformed and validated for each data record
- 99.8% migration accuracy
- Reduced reliance on manual intervention
- Greater consistency across migrations
- A scalable foundation for future PAS consolidation
