Overture

A smarter way to migrate insurance data

Moving off a legacy platform shouldn't mean months of spreadsheets, manual mapping and data analysis. Overture is Simfuni's proprietary AI-powered migration technology, designed to accelerate the complex data work involved in moving onto the Simfuni platform.

AI does the heavy lifting. Migration experts remain in control.

Benefits

Make the path to modernise easier

Start with an intelligent first draft

Turn unfamiliar legacy data into proposed mappings and transformation rules, giving migration teams something intelligent to review instead of starting from a blank spreadsheet.

Focus experts where they matter

Surface ambiguous mappings, data quality issues and exceptions early, so subject matter experts can focus their attention on the decisions that genuinely need human judgement.

Build confidence earlier

Identify mapping questions and data issues throughout the migration process, rather than discovering them late in the project when they are harder to resolve.

Maintain complete control

Keep every mapping reviewable, every transformation reproducible and every output traceable back to its source

Key capabilities

Built for the reality of insurance migration

Insurance data is rarely clean, consistent or well documented. Overture combines AI-assisted analysis with deterministic transformation and validation to help migration teams understand, map and prepare complex legacy data for the Simfuni platform.

Raw data ingestion

Start with source data in the form it actually exists. Overture accepts raw CSV and Excel files without requiring everything to be cleaned and reformatted first

Intelligent schema analysis

Analyse unfamiliar source files to infer their structure, identify likely business meaning and understand relationships across policy, customer, billing and other data.

AI-assisted mapping

Generate proposed source-to-target mappings and transformation rules, giving migration experts a working first draft to review and refine.

Intelligent exception handling

Surface ambiguous mappings and potential data quality issues so expert attention is directed towards the areas where judgement matters most.

Deterministic transformation & validation

Once mappings are approved, apply transformation rules consistently and validate output against the target specification using deterministic, repeatable processes.

Complete traceability

Maintain visibility from transformed output back to the original source data, mapping decision and transformation rule, supporting review, reconciliation and sign-off.

How it works

From raw legacy data to migration-ready output

Overture is built around a simple principle: use AI where interpretation and pattern recognition add value, and deterministic processes where consistency and control matter.

The result is not autonomous migration. It is a better way for experienced migration teams to work.

1. Upload what you have

Start with raw extracts from the legacy environment. Overture analyses the files as they arrive, helping the team understand their structure, content and relationships without requiring extensive preparation upfront.

2. Let AI do the first pass

Overture compares the source data with the Simfuni target model and generates proposed mappings and transformation rules. Straightforward mappings can be identified quickly, while ambiguity is surfaced for review.

3. Put experts in control

Migration specialists and subject matter experts review the proposals, resolve exceptions and refine mappings where required.
The AI proposes. Your experts decide.

4. Transform and validate

Once approved, mappings are executed deterministically across the source data. Overture validates the results and surfaces row-level errors, anomalies and other issues requiring investigation.

5. Review, reconcile and repeat

Every run produces clear evidence of what happened. Teams can resolve issues, rerun the migration and progressively build confidence in the output.

6. Move forward with confidence

Approved, validated data is prepared for migration onto the Simfuni platform, with the mappings, transformation rules and traceability needed to support reconciliation and sign-off.

Your last migration doesn't have to define your next one.
