01 / Challenge
The business problem
Thirty years of account-centric legacy models carried business logic that could not simply be lifted into a new CRM. The migration had to preserve every relationship and historical record without interrupting operations.
02 / Engineering
The approach
We re-engineered the legacy models into scalable relational structures and built validation frameworks that proved parity record by record before production cutover.
03 / Outcome
What changed
A zero-downtime cutover with 100% data parity, zero data loss and the legacy platform decommissioned.
