Overview
Data migration is where legacy system modernisation most often loses time and credibility. Old systems hold years of data with undocumented rules, duplicate records and quality problems nobody has measured, and a new platform will only be trusted if the numbers reconcile on day one. We treat migration as a data problem first and a technical one second. We profile and cleanse the source data, agree mapping and business rules with the people who own the data, rehearse the migration until reconciliation is routine, and plan cutover and fallback with the teams who will run the new service.

Our Approach
How we work.
- 1
Discover
We profile the legacy sources, measure data quality, and agree scope, business rules and success criteria with the people who own the data.
- 2
Prepare
We cleanse and de-duplicate the data, build source-to-target mappings, and design the migration pipelines and reconciliation checks.
- 3
Rehearse
We run trial migrations against production-like data until volumes, timings and reconciliation results are predictable.
- 4
Cut over
We execute the migration to an agreed plan with fallback, validate the result with the business, and support decommissioning of the legacy system.
