Data & Analytics
Data Migration
Migrating data out of a system being replaced, with reconciliation proving nothing was lost or changed. The proof is the deliverable.
In short
Moving records without losing any.
What we deliver
- Field-level mapping agreed before any load
- Dry runs against a copy, with a reconciliation report
- Cutover plan with a tested rollback
- Post-migration verification signed off by the data owner
A good fit when
- A legacy system is being switched off
- A previous migration lost data and nobody noticed for months
- Two companies are merging their records
